After reading a bunch of negative comments here, let me add a little on the bright side. I've been using Thunderbird for many years, currently both at home and at work to manage gmail accounts, pop at home, imap in the office. It works great for me, with a few annoyances but nothing serious.
As for the donations, Thunderbird seems to be somehow apart from Mozilla now, so I don't think much about specific org structure and will gladly donate.
Maybe on paper there're dozens of alternatives, but when I consider my specific requirements, I haven't found anything better, YMMV.
I've been using Thunderbird for decades, I've donated in the past, and am likely to donate again. With that out of the way, the lack of transparency as to what happens to my money kills the incentive to donate.
"How will my gift be used?"
"Thunderbird is the leading open source email and productivity app that is free for business and personal use. Your gift helps ensure it stays that way, and supports ongoing development."
Well that tells me exactly nothing. This might not be as big an issue if they were separate from Mozilla. To be concrete, and focusing only on the development of Firefox, there's now an AI chatbot in the sidebar. I think that's a good addition. However, when the only options are proprietary services, it's hard for me to see the point of Firefox. It would be easier to get out my credit card for Thunderbird if I didn't have those thoughts in the back of my mind. As it stands, my donation might be going to fund the Mozilla CEO's salary.
I find that a weird sentiment. Why do people demand to know and control how every one of their donations goes, while nobody questions how corporations use their money. Ironically, the demand for this increased transparency significantly increases compliance cost, which means more and more money is driven away from the actual cause toward the administrative costs. Exactly what people don't want to support.
The defining difference about paying money to a corporation in exchange for a product is you're paying for something already there, an agreed exchange of value. The whole point about a donation is it's given not in exchange for doing any particular task, but gratuitously.
It's not a weird sentiment to want to know what benefits a gift is providing. That's all people are asking for when they want transparency around donations: tell us how you're benefiting from it so we can feel good about gifting you.
Is it necessary? No. The point being made is that people would be happier and potentially gift more if there was more transparency. If your argument is transparency costs more than the extra gifts then the solution to that is - ironically - be transparent about it and people might gift means to make transparency cheaper and make donations viable.
US nonprofits are as transparent as can get. Their tax returns have to be public record by law. Maybe a press release shared to Hacker News doesn't have the information you want, but you can call them up any time you please and get a detailed categorized line items of everything they spend money on, or use any number of aggregator services that publish IRS Form-990s for free on the web. You can also get it directly from the IRS itself, which has a searchable database. Here is Mozilla's tax return for 2024: https://apps.irs.gov/pub/epostcard/cor/200097189_202412_990_...

"I bought you tickets for your favorite artist for your birthday. I expect a detailed trip report" :)
Yes, you're right, personal gifts aren't donations, but then maybe we should stop calling donations gifts, too. Gifts are given without any expectations attached. Donations do and should have expectations.
If Thunderbird required users to sign up for an annual subscription, then that specific problem -- not being able to tell what good one's payment would do -- would go away. There would be a very specific reason to pay the money.
(In practice, they presumably couldn't do that, at least not effectively, because the code is open source and someone else could fork it. But let's imagine that somehow they could require all Thunderbird users to pay them.)
That doesn't, of course, mean that it would be better overall. Thunderbird users would go from getting Thunderbird for free and maybe having reason to donate some money, to having to pay some money just to keep the ability to use Thunderbird: obviously worse for them. There'd probably be more money available for Thunderbird development, which would be good. The overall result might be either good or bad. But it would, indeed, no longer be unclear whether and why a Thunderbird user might choose to pay money to the Thunderbird project.
> Instead, people act like they're buying in to a 50% share with their $5 and then act like they cofounded the project forever after the donation.
You've twisted the timing. My comment is about
"Give me money." "Okay, tell me why I should give you money."
not
"I gave you money. Tell me what you did with it." It's a big difference. It's easy for me to just not give them money if I don't know what I'm donating to.
Those two examples map to the first and second parts of my claim.
Though I'm making a general reflection rather than trying to antagonize any individual here. I was already thinking about this when clicking into TFA to see that yes, it's another donation beg.
The answer to the person I replied to is basically: yes.
There's a nit in human psychology between mutual transactions (even lopsided against our favor) and voluntary unilateral ones (like donations) where the latter results in disproportionate scrutiny and entitlement compared to the former.
I once started accepting donations on my forum. I noticed people acted like they were about to make the grandest gesture in the world, would I be so lucky to deserve it after answering their questions despite having built a forum they spend four hours a day on. (They gave me $5)
And once they donated, they saw themselves as a boardmember-like persona with veto power and a disproportionate say on what I do, often pointing out that they're a donor. (They gave me $5)
I'm exaggerating a bit to paint a picture of what I mean. I think it's all unintentional, and they might be embarrassed if I'd told them this.
But I ended up refunding everyone after a while.
Yet when I charged $5 to let users expand their PM inbox size or max avatar resolution, nobody ever brought it up. They understood the transaction ended there. What is the $5 used for? -- What do you mean? It doubled my PM inbox size.
It's a funny quirk of our brain. I think a license purchase aligns expectations much more than groveling for donations, and it creates a natural freemium model for open source (or source-available rather?) projects.
When you're shopping for a paid product, you're generally trying to minimize your costs (while balancing quality). When you're donating to a free product, you're actually trying to maximize the effectiveness of your donation. If you were simply trying to minimize your cost/benefit ratio, you would donate nothing. Clearly there is a totally different mentality at play.
Consider it also from the recipient's perspective. Their benefactors are more likely to donate more money when they believe it will be put to good use. It's a complicated messaging problem, but being vague is probably not in your best interest.
Exactly. I decided to never donate to Wikipedia again after learning that wikipedia took some of that donated money and redonated it to other companies.
It felt like a betrayal to me.
Not that I think the other companies were bad, but if they have so much money they're giving it away to other people then they obviously don't need my money anymore.
If they wanted people to give other companies money then why didn't they have a separate different begging drive for those companies instead of just deciding, "Well, this is my money now, given to me to keep the site running and our employees paid, I'm going to give it away instead of using for the purpose that I literally begged it for".
A Boeing 777 burns 300g of fuel per second per engine, while taxiing on the ground... so 2 gallons gets you somewhere between 10 and 15 seconds of taxiing.
The reason "nobody questions how corporations use their money" is that in 99.9% of cases when I pay a corporation money for a product, I'm doing it not for the sake of what they can do with the money, but because otherwise I don't get to use the product, at least not legally.
If instead I donate to an open-source project, I'm not doing it in order to get access to the product; I already have that. I'm doing it because I hope they will do something with the money that I value. (Possible examples: Developing new features I like. Rewarding people who already developed features I liked. Activism for causes I approve of. Continuing to provide something that benefits everyone and not just me.)
And so I care a lot what they're going to do with the money, in a way I don't if I (say) pay money to Microsoft in exchange for the right to use Microsoft Office. Because what they're going to do with the money determines what point there is in my giving it.
Sometimes, everything the project does is stuff I think is valuable (for me or for the world). In that case I don't need to ask exactly what they're doing. Sometimes, it's obvious that what happens to the money is that it goes into the developer's pockets and they get to do what they like with it. In that case, I'll donate if the point of my donation is to reward someone who is doing something I'm glad they're doing, and probably not otherwise.
In the case of Thunderbird, it's maybe not so obvious. Probably the money will go toward implementing Thunderbird features and bug fixes, but looking at the history of Firefox I might worry that that's going to mean "AI integrations that actual users mostly don't want" or "implementing advertising to help raise funds", and I might have a variety of attitudes to those things. Or it might go toward some sort of internet activism, and again I might have a variety of attitudes to that depending on exactly what they're agitating for. Or maybe I might worry that the money will mostly end up helping to pay the salary of the CEO of Mozilla. (I don't think that's actually possible, but I can imagine situations where Mozilla wants some things done, and if they can pay for them via donations rather than using the company's money they'll do so, so that the net effect of donating is simply to increase Mozilla's profits.)
And I don't think anyone's asking for anything very burdensome in the way of transparency. Just more than, well, nothing at all which is what we have at the moment. The text on the actual page says literally nothing beyond "help keep Thunderbird alive". The FAQ says "Thunderbird is the leading open source email and productivity app that is free for business and personal use. Your gift helps ensure it stays that way, and supports ongoing development." which tells us almost nothing. And "MZLA Technologies Corporation is a wholly owned for-profit subsidiary of the Mozilla Foundation and the home of Thunderbird." which tells us that donations go to a for-profit subsidiary of the Mozilla Foundation (which I believe is the same entity that owns the Mozilla Corporation, but like most people I am not an expert on this stuff and don't know what that means in practice about how the Mozilla Foundation, the Mozilla Corporation and MZLA Technologies Corporation actually work together).
Maybe donated money will lead to MZLA Technologies Corporation hiring more developers or paying existing developers more? Maybe it'll be used to buy equipment, or licences for patented stuff? Maybe it'll be used to advertise Thunderbird and get it more users? Maybe it'll be used to agitate for the use of open email standards or something like that? Maybe. Maybe some other thing entirely. There's no way to get any inkling.
This in a larger perspective at least, IS a problem for NGO:s from what i know. That donors seems to be much more careful where they money go when its in the form of a donation. I dont know about open source project specifics here. I totally get what you mean and probably mostly agree as well, but the money you give to corporations have consequences as well. You can for example fund a company you have strong moral disagreements with without knowing or miss a company that you would want to support for the opposite reasons.
With that said I also think we should expect more then "it helps fund the development". Its not that difficult to write a couple paragraphs more and be a little more specific. Then again, maybe they get so little in donations that they cant really say how the money will be used and its more of a "buy me a beer" type of thing to keep the developers happy. Unless suddenly people start giving more and a developer actually could invest more hours in the project.
Mozilla and Wikipedia for example are causes I support. But why would I give money to them if they are going to turn around and give money to some cause I don't support (OR am actively against)? These non-profits love to shuffle money around to unrelated causes. As a non profit, supporting open source software, I think expecting a large percentage of the donation to go to engineering and not admin, social causes, etc. is a reasonable expectation.
Yes that's all reasonable but the comparison is paying for (or giving them other revenue) corporations who also love to shuffle money around and can support causes you are actively against. The point being made was that people give causes trying to improve society more scrutiny than they give for-profit mega corporations who have in the past shown that they use their money for a lot of things detrimental to society.
Assuming there is a healthy market, then you have alternatives you can purchase your products and goods from. These alternatives may have other trade-offs and in fact, there may well be open and closed alternatives as well as hybrid options.
Some people simply want the "best fit" solution for a product. IMO, this used to be Outlook+Exchange, hands down... M365 scaling has enshittified the bundle in a lot of ways leaving a wide gap for alternatives. Google's GMail is a leading alternative that is a closed service. Thunderbird is an open solution that solves part of the problem (shared calendars/contacts only having half the solution).
When you pay for a product, you often are able to give feedback and request for features... the expectation is that you are getting value for what you are paying and that the company continues to do so while adding features that add more value in time.
When you donate to an open-source project, and that project redirects funds to have a multi-million dollar marketing event that only benefits middle managers and seeks to add revenue with features the majority of donors oppose, then someone who would otherwise support the development might rightly feel a bit betrayed or choose not to donate altogether, much like someone might not purchase a given product or service from a company that does what they feel are bad things.
It's not dramatically different, it's just when/where the individual might expect a level of transparency, value or direction. A purchase is against existing value... a donation is against future value.
I think we're talking past each other. I am not saying that people shouldn't be upset that if they donate to an organization that a large portion of that money might go to things they rather that organization not do. Like a $100 donation might have $20 of overhead or waste.
What I don't get is why people don't think the same for for-profit enterprises. If I spend $120 a year on some SaaS, I don't ask what portion of that goes into the CEOs pocket who might use that money to buy politicians to advance tax policy they prefer, or government contracts against the public interest, etc.
It's not about the expected value of a product, it's about what else your money funds when you hand it over to a corporation that people rarely consider. They should consider it just as much as they consider donations to non-profits.
Also, the assumption of a healthy market is not one I would take. A lot of corporate money is spent on regulatory capture and other ways to prevent a healthy market. Funded by customer spend. A purchase is against future value in the same way that past purchases are what allow companies today to make markets less healthy.
While I get what you're saying, I think it's exactly in that the expectations are different between a donation and a payment for product/service.
You pay for an existing product/service and expect that product/service to be fit for a need... that's generally it as far as expectations go... some may actually care about a company being a bad actor and boycott etc, but that's secondary in and of itself. You immediately get the product or service that exists.
A donation, is against expectations for results... though there may be other reasons to donate to a cause/charity.
When the product is in dire state but the company does unnecessary things and increase CEO salary YoY with ever declining userbase, yes... Maybe the people who donates want to know. Am talking about Firefox there BTW. So it's absolutely understandable that people want to know.
Investors do very much question how corporations use their money, and that is why corporations publish quarterly financial statements and have shareholder meetings and hire accountants and auditors. Investors want to make sure that they're going to get their investment back plus profit and thus care about a company's balance sheet. Any financial transparency in non-profit donations is derived from the financial transparency required by for-profit investments.
When making purchasing decisions lots of people look beyond the utility of the product to the broader behaviour of the corporation and how it impacts society. I know people who've been avoiding Nestlé for decades.
When I pay money to buy food I don't need to ask how the shop is going to use that money: I gave money, I got food.
If I am going to donate money to a company/NGO that wants to buy food for poor people, of course I am interested in knowing how much of that money is going to salaries, how much into activities of sort, and how much in actually feeding people.
> Ironically, the demand for this increased transparency significantly increases compliance cost, which means more and more money is driven away from the actual cause toward the administrative costs.
I disagree.
If you are asking people for donations, then it is only fair that you provide transparency.
Donations are made out of pure goodwill. It is not like buying a widget from $megacorp.
I do not buy the "increased administrative costs" argument either. At a bare minimum all it would take is 5 minutes a month and a simple spreadsheet.
Well for one, when you purchase something from a corporation, you know where the money went because you got the thing or access to the service you just paid for. With a donation you don't have that and because you're donating you probably care about whatever subject you want to improve so you'd like to know that is were your money is going instead of finding out later it just went to the CEO of whatever to blow on blackjack and hookers.
In the case of Mozilla, you actually know donating to the Mozilla Foundation does not in any way benefit Firefox or Thunderbird, which is probably the whole reason you were actually donating in the first place. Donating to the Mozilla Foundation funds all the pointless side projects they they decide to pick up and pay the CEO quite frankly an undeservedly large salary.
Exactly what I've been saying when people complain about how public sector spends the taxes (especially when comparing against private sector so-called efficiency when managing hospitals or schools)
I have the same beef with the Signal Foundation. A few years ago, I engaged with the new CEO when she was soliciting donations and asked whether they were going to publish any kind of high-level feature roadmap. I explained that there were a few features I was really looking forward to, and that I’d even written some code that might help expedite them getting rolled in. She told me that stuff like publishing roadmaps takes time and resources they don’t have.
I mean, as I've somewhat said above, I do donate to Mozilla for a direct-but-big reason. Overall, I find their work VERY important. I acknowledge that they've never been perfect, but I've watched what they've done for 20-30 years and strongly trust that generally, they're doing good things with my money because that's what they've been doing.
Thunderbird, separate from Mozilla, I don't think has that to rely on. That does feel more like "why should I give money to this project that (for me) has been pretty mid at maintaining a popular piece of software?"
CEO of MZLA (the Mozilla entity that develops Thunderbird). One point of clarification, we don't get money from any source but our donors. After years of funding issues, MZLA was created by the Mozilla Foundation and the Thunderbird Council (our community governance body), to provide a legal/financial home for Thunderbird.
Launching Thundermail this year (an email service) which we hope to help provide even more funds for development, beyond just donations. Also serving a user need (lots of our users ask us to help them get off Gmail).
Lots of interest in how the money is spent - answer: mostly on devs, landed Exchange support recently (big for a lot of MS users), working on Graph support as well, JMAP after that. Updating the calendar (primarily UX/UI there), continuing to improve our Android app, working on a native iOS app and the aforementioned Thundermail service.
We publish yearly reports and will publish one again this year detailing all this.
Happy to answer questions and we are an open source project so feel free to reach out to us and engage if you really want to see how the sausage is made!
*Edit: More context on what Thunderbird Council is*
Campaigns like this need more info. This page doesn't answer any basic questions.
How much money do you currently get? How much money do you need and how will you use it? Does it even go directly to Thunderbird development or will be used up by Mozilla for other projects?
Still, my point stands that communication around it should be super clear and available on all pages where they collect money. It shouldn't require me to search for it.
> MZLA Technologies Corporation is a wholly owned for-profit subsidiary of the Mozilla Foundation and the home of Thunderbird.
I guess I don't understand why the open-source email client with zero revenue potential is managed by a for-profit subsidiary, nor why that for-profit subsidiary is begging for donations.
Shouldn't this whole thing be managed by the non-profit Mozilla Foundation?
I wish Thunderbird fix their plain text editor (it is at level of old Notepad, and chrome for it looks ugly, and line wrapping is a mess, especially with in-line quotation), add ability to store Folder properties (including Identity used for this folder, retention period and such) as IMAP properties and not locally to have same settings on different devices.
And, yes, proper support for Sieve, including per-folder Sieve. Sieve is a pain after they changed something and 3rd party Sieve plugin died (become Electorn Application).
Now Thunderbird has so many rough edges (I named only my top-3, but I'm sure anybody can add others!), but still one and only usable cross-platform e-mail client.
Oh, yes, development pace is unbearable slow: after killing "Manually sort folders" plugin it takes more than year (!) to add this as "core" feature with huge help from aforementioned plugun's author. Very slow process of review, integrating, releasing which takes MONTHS to integrate ready feature. It should be very discouraging for contributors.
Thunderbird now provide like 10% of features of old and almost forgotten (but still alive) windows-only client "The Bat!" from end of 1990s, beginning of 2000s and was written by team of like 5 people.
I thought you were owned by Mozilla? A corporation that has over half a billion dollars in yearly revenue? If they decided to allocate zero funding to you, wouldn't it be vastly more effective to start some sort of campaign/movement (either internal or external) to get that funding back, or to entirely fork and leave Mozilla to be your own independent project, than to ask for random donations?
Just donated. Have been using Thunderbird for years. I once donated to Wikipedia - and they have billions I heard - so might as well donate to another important piece of software for my digital life.
Now that I read the comments I find out Mozilla might have enough money and a CEO taking in millions. Any recommendations for a good email client on Linux? Just as a backup for now...
I installed Thunderbird for the first time in a couple of decades recently. My impression was that it's very feature rich but also quite ugly and not friendly to new users. It comes with a lot of assumptions about what the user wants to do and how, and I found myself having to use cheats and workarounds from the outset. I wanted to import a batch of disparate .eml files that had been seperately exported, and after 15 minutes I was starting to think it might have been easier to just do it in Python.
I also didn't care for the tabbed panels, which make it feel as if the entire thing was just ported from a browser. It really needs some fresh design and user interface work.
Interestingly, I used Thunderbird for years, it was really the best client for some times on Linux. But as the development stalled, I moved to Gnome Evolution, the nice integration with the general Gnome desktop made the switch less painful (at the start, it was hard, Evolution was not that good). But Evolution improved nicely, less bugs, faster, still well integrated into the desktop and I see no reasons to switch back to another tool.
The only change in my workflow is that now, I am also using in parallel a stupid command line tool "vibe coded" in Python to read my emails. It allows me to quickly check my emails out of VS Code in a Claude Code session, a bit like when I was doing my emails directly in Emacs :-)
I seem to remember an article in lwn a year or so ago about them hiring a new PM who was basically a donation campaign manager, and one of the points was "telemetry is good, actually, and should be opt out not opt in."
I get the feeling the amount they fundraise is more a quarterly target than a requirement, but I could be wrong. All of mozilla gives me a bad taste recently.
I wish I could use Thunderbird at work now that it has Exchange support . Unfortunately we're mandated to use Microsoft Outlook. Outlook feels like it has completely been forgotten by Microsoft. I don't recall the last time they updated anything meaningful in the product (at least on macOS), it's quite a mess of a product. Wishing Thunderbird all the best it's the competition we need.
If you press the browser’s back button on the donation page, they send you to a page pestering you for your email address so they can send you a reminder to donate later. Talk about a dark pattern.
Mozilla has really gone off the rails. An organisation who claims to work on behalf of the user and who makes a web browser, actively hijacking the user experience to peddle for a few dollars?
Why the heck is Thunderbird “fully funded by financial contributions from [their] users”? Where do the billions of dollars from Google go? All the stupid doomed side projects which no one asked for nor wants and are abandoned after one year?
Why mozilla doesn't approach a similar strategy with firefox? I see with thunderbid most of the recent focus is in making the product better and the raising of the funding it's focused on user donations.
With Firefox the focus is not in making the product better and instead on adding useless features, and the raising of funding is focused in advertising and random quests not related to the browser
Long shot, but I'll ask. For a while Thunderbird spam filter will work fine. Then, spontaneously, it stops working and starts showing me many which are obvious, identical junk. And after flagging them as junk, it doesn't seem to learn anything.
For when this happens, it would be nice to have an explicit (and easy) way to blacklist items. Creating new filters for each of them is too involved.
I wish there was a system that lets users put up a donation that is released once a specific bug is fixed or a specific feature is implemented.
Wouldn't that be cool? The company would have a list of tasks with a dollar amount next to it.
I for one have been dabbling with a bug in ThunderBird for days now that drives me mad:
I recently created a folder in Thunderbird and called it "archive". No way would I have expected that this will lead me to a bug and will take hours out of my day: There seems to be no way to get rid of this folder anymore.
Things I have tried:
"Keep message archives in" in "Copies and Folders" is disabled. I tried temporarily enabling it, setting it to some other dir and disabling it again, that did not help.
I have disabled it in "subscribe".
I cannot rename it.
There is no "archive" folder in the web interface of my email provider, so if it Thunderbird somehow created it on the server, there seems to be no way to see, let alone delete it again in the web interface.
I tried deleting archive.msf on disk. That makes the folder disappear after the next start, but it is recreated after about a second.
I deleted folderTree.json and folderCache.json, that did not help.
The other day I cam to my computer with Thunderbird showing me a full page screen instead of my email list that I had open before. Not going to donate to projects that disrespect users like that - my computer is not your advertising space even if you consider your ads "helpful information".
I've just donated. I use Thunderbird every day and have used it for years now. Mozilla, Firefox and Thunderbird are very important to me and my internet usage. For all the complaints (many just unwarranted in my opinion) I'm a happy user.
I tried for a long time to work with Thunderbird, but what kept bothering me was that I couldn’t simply define keyboard shortcuts. In the end, I landed on AERC and created my own extreme Vim-style keyboard configuration (the idea is to look at the list of mails like looking at a buffer in vim) for it. I’ve never been this fast when it comes to email.
I'm gonna say it: we need to build a Thunderbird replacement. It's got too much technical debt. It can't convert new users. We need something that does.
I really don’t understand the structure that Mozilla has setup here where Thunderbird lives under their for-profit branch, but is so dependent on donations. I remember reading they were considering charging for Thunderbird services when the move was announced 6 years ago, but as far as I can tell, nothing has happened and they’re still desperate for funding.
Now not only does it still need donations, the tax exemption for donors has evaporated. Great.
I use Thunderbird on both Linux/Android as my sole client for personal email. I'm mostly pretty happy with it, aside from search. My use case is mostly receiving email rather than sending email however. I would be much more amenable to donating if I knew that my donation would be going to support Thunderbird specifically and not rolled up into the parent MZLA Technologies Corporation, but I understand that's usually impractical.
Thunderbird will provider their PRO services using stalw.art as email backend. I was considering using it too to replace really old mail system in our company. It looked like modern stack using jmap, but it seems thunderbird actually does not support jmap? Or is it only in their PRO extension? Does it mean I cannot use this unless it is with their services? I'm confused.
Of course there is still IMAP, but I hoped for better.
Torn about this due to multiple factors...but I think the core reasoning remains: if it's a tool you like, there are actual people working on it, and if you want those actual people to stay employed and continue working on the tool, it's in your best interest to do things like donate and talk/share about them.
Is there still no way to export and import your filters in Thunderbird? This is why I shunned it 20 years ago. The absurd idea that you're going to manually run around to all your computers all the time and manually set up (and maintain) mail filters should have been rejected in version 1.0.
I recently started using Thunderbird for work which uses O365 (horrific service) for mail. I've found that 2FA with O365 to be totally unreliable no matter the client, even using the iOS app.
Does anyone use Thunderbird with Gmail and 2FA, and does it work correctly 100% of the time there?
The law of Software Envelopment. Jamie Zawinski in 1995 stated that "software inevitably expands to include email functionality, or it is replaced by software that does"
Clearly, that's not the case anymore. Nowadays you just swap out "email" for "LLM"
In this thread, a bunch of people complaining about an open source app not asking for donations the right way but will be the first people to ask "Why didn't they stick a donate button on the website" or "they should have asked for money!"

As for the donations, Thunderbird seems to be somehow apart from Mozilla now, so I don't think much about specific org structure and will gladly donate.
Maybe on paper there're dozens of alternatives, but when I consider my specific requirements, I haven't found anything better, YMMV.
"How will my gift be used?"
"Thunderbird is the leading open source email and productivity app that is free for business and personal use. Your gift helps ensure it stays that way, and supports ongoing development."
Well that tells me exactly nothing. This might not be as big an issue if they were separate from Mozilla. To be concrete, and focusing only on the development of Firefox, there's now an AI chatbot in the sidebar. I think that's a good addition. However, when the only options are proprietary services, it's hard for me to see the point of Firefox. It would be easier to get out my credit card for Thunderbird if I didn't have those thoughts in the back of my mind. As it stands, my donation might be going to fund the Mozilla CEO's salary.
It's not a weird sentiment to want to know what benefits a gift is providing. That's all people are asking for when they want transparency around donations: tell us how you're benefiting from it so we can feel good about gifting you.
Is it necessary? No. The point being made is that people would be happier and potentially gift more if there was more transparency. If your argument is transparency costs more than the extra gifts then the solution to that is - ironically - be transparent about it and people might gift means to make transparency cheaper and make donations viable.
> It's not a weird sentiment to want to know what benefits a gift is providing.
"I bought you tickets for your favorite artist for your birthday. I expect a detailed trip report" :)
Yes, you're right, personal gifts aren't donations, but then maybe we should stop calling donations gifts, too. Gifts are given without any expectations attached. Donations do and should have expectations.
But nobody wants to hear that they gave those tickets to their pimp, either.
(In practice, they presumably couldn't do that, at least not effectively, because the code is open source and someone else could fork it. But let's imagine that somehow they could require all Thunderbird users to pay them.)
That doesn't, of course, mean that it would be better overall. Thunderbird users would go from getting Thunderbird for free and maybe having reason to donate some money, to having to pay some money just to keep the ability to use Thunderbird: obviously worse for them. There'd probably be more money available for Thunderbird development, which would be good. The overall result might be either good or bad. But it would, indeed, no longer be unclear whether and why a Thunderbird user might choose to pay money to the Thunderbird project.
Instead, people act like they're buying in to a 50% share with their $5 and then act like they cofounded the project forever after the donation.

You've twisted the timing. My comment is about
"Give me money." "Okay, tell me why I should give you money."
not
"I gave you money. Tell me what you did with it." It's a big difference. It's easy for me to just not give them money if I don't know what I'm donating to.
Though I'm making a general reflection rather than trying to antagonize any individual here. I was already thinking about this when clicking into TFA to see that yes, it's another donation beg.
The answer to the person I replied to is basically: yes.
There's a nit in human psychology between mutual transactions (even lopsided against our favor) and voluntary unilateral ones (like donations) where the latter results in disproportionate scrutiny and entitlement compared to the former.
I once started accepting donations on my forum. I noticed people acted like they were about to make the grandest gesture in the world, would I be so lucky to deserve it after answering their questions despite having built a forum they spend four hours a day on. (They gave me $5)
And once they donated, they saw themselves as a boardmember-like persona with veto power and a disproportionate say on what I do, often pointing out that they're a donor. (They gave me $5)
I'm exaggerating a bit to paint a picture of what I mean. I think it's all unintentional, and they might be embarrassed if I'd told them this.
But I ended up refunding everyone after a while.
Yet when I charged $5 to let users expand their PM inbox size or max avatar resolution, nobody ever brought it up. They understood the transaction ended there. What is the $5 used for? -- What do you mean? It doubled my PM inbox size.
It's a funny quirk of our brain. I think a license purchase aligns expectations much more than groveling for donations, and it creates a natural freemium model for open source (or source-available rather?) projects.
Consider it also from the recipient's perspective. Their benefactors are more likely to donate more money when they believe it will be put to good use. It's a complicated messaging problem, but being vague is probably not in your best interest.
It also isn't that unusual for donations to be ring fenced for certain things.
It felt like a betrayal to me.
Not that I think the other companies were bad, but if they have so much money they're giving it away to other people then they obviously don't need my money anymore.
If they wanted people to give other companies money then why didn't they have a separate different begging drive for those companies instead of just deciding, "Well, this is my money now, given to me to keep the site running and our employees paid, I'm going to give it away instead of using for the purpose that I literally begged it for".
If instead I donate to an open-source project, I'm not doing it in order to get access to the product; I already have that. I'm doing it because I hope they will do something with the money that I value. (Possible examples: Developing new features I like. Rewarding people who already developed features I liked. Activism for causes I approve of. Continuing to provide something that benefits everyone and not just me.)
And so I care a lot what they're going to do with the money, in a way I don't if I (say) pay money to Microsoft in exchange for the right to use Microsoft Office. Because what they're going to do with the money determines what point there is in my giving it.
Sometimes, everything the project does is stuff I think is valuable (for me or for the world). In that case I don't need to ask exactly what they're doing. Sometimes, it's obvious that what happens to the money is that it goes into the developer's pockets and they get to do what they like with it. In that case, I'll donate if the point of my donation is to reward someone who is doing something I'm glad they're doing, and probably not otherwise.
In the case of Thunderbird, it's maybe not so obvious. Probably the money will go toward implementing Thunderbird features and bug fixes, but looking at the history of Firefox I might worry that that's going to mean "AI integrations that actual users mostly don't want" or "implementing advertising to help raise funds", and I might have a variety of attitudes to those things. Or it might go toward some sort of internet activism, and again I might have a variety of attitudes to that depending on exactly what they're agitating for. Or maybe I might worry that the money will mostly end up helping to pay the salary of the CEO of Mozilla. (I don't think that's actually possible, but I can imagine situations where Mozilla wants some things done, and if they can pay for them via donations rather than using the company's money they'll do so, so that the net effect of donating is simply to increase Mozilla's profits.)
And I don't think anyone's asking for anything very burdensome in the way of transparency. Just more than, well, nothing at all which is what we have at the moment. The text on the actual page says literally nothing beyond "help keep Thunderbird alive". The FAQ says "Thunderbird is the leading open source email and productivity app that is free for business and personal use. Your gift helps ensure it stays that way, and supports ongoing development." which tells us almost nothing. And "MZLA Technologies Corporation is a wholly owned for-profit subsidiary of the Mozilla Foundation and the home of Thunderbird." which tells us that donations go to a for-profit subsidiary of the Mozilla Foundation (which I believe is the same entity that owns the Mozilla Corporation, but like most people I am not an expert on this stuff and don't know what that means in practice about how the Mozilla Foundation, the Mozilla Corporation and MZLA Technologies Corporation actually work together).
Maybe donated money will lead to MZLA Technologies Corporation hiring more developers or paying existing developers more? Maybe it'll be used to buy equipment, or licences for patented stuff? Maybe it'll be used to advertise Thunderbird and get it more users? Maybe it'll be used to agitate for the use of open email standards or something like that? Maybe. Maybe some other thing entirely. There's no way to get any inkling.
With that said I also think we should expect more then "it helps fund the development". Its not that difficult to write a couple paragraphs more and be a little more specific. Then again, maybe they get so little in donations that they cant really say how the money will be used and its more of a "buy me a beer" type of thing to keep the developers happy. Unless suddenly people start giving more and a developer actually could invest more hours in the project.
Some people simply want the "best fit" solution for a product. IMO, this used to be Outlook+Exchange, hands down... M365 scaling has enshittified the bundle in a lot of ways leaving a wide gap for alternatives. Google's GMail is a leading alternative that is a closed service. Thunderbird is an open solution that solves part of the problem (shared calendars/contacts only having half the solution).
When you pay for a product, you often are able to give feedback and request for features... the expectation is that you are getting value for what you are paying and that the company continues to do so while adding features that add more value in time.
When you donate to an open-source project, and that project redirects funds to have a multi-million dollar marketing event that only benefits middle managers and seeks to add revenue with features the majority of donors oppose, then someone who would otherwise support the development might rightly feel a bit betrayed or choose not to donate altogether, much like someone might not purchase a given product or service from a company that does what they feel are bad things.
It's not dramatically different, it's just when/where the individual might expect a level of transparency, value or direction. A purchase is against existing value... a donation is against future value.
What I don't get is why people don't think the same for for-profit enterprises. If I spend $120 a year on some SaaS, I don't ask what portion of that goes into the CEOs pocket who might use that money to buy politicians to advance tax policy they prefer, or government contracts against the public interest, etc.
It's not about the expected value of a product, it's about what else your money funds when you hand it over to a corporation that people rarely consider. They should consider it just as much as they consider donations to non-profits.
Also, the assumption of a healthy market is not one I would take. A lot of corporate money is spent on regulatory capture and other ways to prevent a healthy market. Funded by customer spend. A purchase is against future value in the same way that past purchases are what allow companies today to make markets less healthy.
You pay for an existing product/service and expect that product/service to be fit for a need... that's generally it as far as expectations go... some may actually care about a company being a bad actor and boycott etc, but that's secondary in and of itself. You immediately get the product or service that exists.
A donation, is against expectations for results... though there may be other reasons to donate to a cause/charity.
If I donate, I want more devs getting paid, not a CEO parasiting the non-profit.
If you're asking for donations and holding your cap out, the implication is that every penny will go toward development.
Mozilla should either just make it a product that you have to pay for, or sub to, or keep donations cleanly separated.
If I am going to donate money to a company/NGO that wants to buy food for poor people, of course I am interested in knowing how much of that money is going to salaries, how much into activities of sort, and how much in actually feeding people.
> Ironically, the demand for this increased transparency significantly increases compliance cost, which means more and more money is driven away from the actual cause toward the administrative costs.
I disagree.
If you are asking people for donations, then it is only fair that you provide transparency.
Donations are made out of pure goodwill. It is not like buying a widget from $megacorp.
I do not buy the "increased administrative costs" argument either. At a bare minimum all it would take is 5 minutes a month and a simple spreadsheet.
In the case of Mozilla, you actually know donating to the Mozilla Foundation does not in any way benefit Firefox or Thunderbird, which is probably the whole reason you were actually donating in the first place. Donating to the Mozilla Foundation funds all the pointless side projects they they decide to pick up and pay the CEO quite frankly an undeservedly large salary.

Gah!
> Your gift helps ensure it stays that way
Written this way, it sounds like "donate or we'll have to make you pay for it"
Thunderbird, separate from Mozilla, I don't think has that to rely on. That does feel more like "why should I give money to this project that (for me) has been pretty mid at maintaining a popular piece of software?"
Launching Thundermail this year (an email service) which we hope to help provide even more funds for development, beyond just donations. Also serving a user need (lots of our users ask us to help them get off Gmail).
Lots of interest in how the money is spent - answer: mostly on devs, landed Exchange support recently (big for a lot of MS users), working on Graph support as well, JMAP after that. Updating the calendar (primarily UX/UI there), continuing to improve our Android app, working on a native iOS app and the aforementioned Thundermail service.
We publish yearly reports and will publish one again this year detailing all this.
Here is a 2025 recap: https://blog.thunderbird.net/2025/12/thunderbird-2025-review...
But the blog has a ton of updates across the different efforts: https://blog.thunderbird.net
Happy to answer questions and we are an open source project so feel free to reach out to us and engage if you really want to see how the sausage is made!
*Edit: More context on what Thunderbird Council is*
How much money do you currently get? How much money do you need and how will you use it? Does it even go directly to Thunderbird development or will be used up by Mozilla for other projects?
Edit: I found some info here: https://www.thunderbird.net/en-US/donate/
Still, my point stands that communication around it should be super clear and available on all pages where they collect money. It shouldn't require me to search for it.
Works perfect, I even migrated my Windows install to Linux just by copying the data folder, absolutely seamless.
Not sure why people are hating on it so much here. Point to an alternative with the same features?
> MZLA Technologies Corporation is a wholly owned for-profit subsidiary of the Mozilla Foundation and the home of Thunderbird.
I guess I don't understand why the open-source email client with zero revenue potential is managed by a for-profit subsidiary, nor why that for-profit subsidiary is begging for donations.
Shouldn't this whole thing be managed by the non-profit Mozilla Foundation?
And, yes, proper support for Sieve, including per-folder Sieve. Sieve is a pain after they changed something and 3rd party Sieve plugin died (become Electorn Application).
Now Thunderbird has so many rough edges (I named only my top-3, but I'm sure anybody can add others!), but still one and only usable cross-platform e-mail client.
Oh, yes, development pace is unbearable slow: after killing "Manually sort folders" plugin it takes more than year (!) to add this as "core" feature with huge help from aforementioned plugun's author. Very slow process of review, integrating, releasing which takes MONTHS to integrate ready feature. It should be very discouraging for contributors.
Thunderbird now provide like 10% of features of old and almost forgotten (but still alive) windows-only client "The Bat!" from end of 1990s, beginning of 2000s and was written by team of like 5 people.
But still, I've donated!
> We don’t have corporate funding
I thought you were owned by Mozilla? A corporation that has over half a billion dollars in yearly revenue? If they decided to allocate zero funding to you, wouldn't it be vastly more effective to start some sort of campaign/movement (either internal or external) to get that funding back, or to entirely fork and leave Mozilla to be your own independent project, than to ask for random donations?
Now that I read the comments I find out Mozilla might have enough money and a CEO taking in millions. Any recommendations for a good email client on Linux? Just as a backup for now...
I also didn't care for the tabbed panels, which make it feel as if the entire thing was just ported from a browser. It really needs some fresh design and user interface work.
The only change in my workflow is that now, I am also using in parallel a stupid command line tool "vibe coded" in Python to read my emails. It allows me to quickly check my emails out of VS Code in a Claude Code session, a bit like when I was doing my emails directly in Emacs :-)
Mozilla is managing Thunderbird as a second class citizen since way too long.
I get the feeling the amount they fundraise is more a quarterly target than a requirement, but I could be wrong. All of mozilla gives me a bad taste recently.
Mozilla has really gone off the rails. An organisation who claims to work on behalf of the user and who makes a web browser, actively hijacking the user experience to peddle for a few dollars?
Why the heck is Thunderbird “fully funded by financial contributions from [their] users”? Where do the billions of dollars from Google go? All the stupid doomed side projects which no one asked for nor wants and are abandoned after one year?
It's basically in maintenance mode. Are they trying to add features nobody really wants to justify their existence, like Mozilla?

For when this happens, it would be nice to have an explicit (and easy) way to blacklist items. Creating new filters for each of them is too involved.
Wouldn't that be cool? The company would have a list of tasks with a dollar amount next to it.
I for one have been dabbling with a bug in ThunderBird for days now that drives me mad:
I recently created a folder in Thunderbird and called it "archive". No way would I have expected that this will lead me to a bug and will take hours out of my day: There seems to be no way to get rid of this folder anymore.
Things I have tried:
"Keep message archives in" in "Copies and Folders" is disabled. I tried temporarily enabling it, setting it to some other dir and disabling it again, that did not help.
I have disabled it in "subscribe".
I cannot rename it.
There is no "archive" folder in the web interface of my email provider, so if it Thunderbird somehow created it on the server, there seems to be no way to see, let alone delete it again in the web interface.
I tried deleting archive.msf on disk. That makes the folder disappear after the next start, but it is recreated after about a second.
I deleted folderTree.json and folderCache.json, that did not help.

Now not only does it still need donations, the tax exemption for donors has evaporated. Great.
Either way, they have more information on their donate page as well as a whole knowledge base set of pages:
https://www.thunderbird.net/en-US/donate/#faq
https://give.thunderbird.net/hc/en-us
Of course there is still IMAP, but I hoped for better.
Does anyone use Thunderbird with Gmail and 2FA, and does it work correctly 100% of the time there?
Clearly, that's not the case anymore. Nowadays you just swap out "email" for "LLM"
