Addressing the usual few complaints folks always bring up:
* This is from the separate independent team that works on Thunderbird, not Firefox, so there isn't any resource contention happening there
* Thunderbird is revenue positive, and this potentially gives that team another revenue stream to be even more self-sustaining through charging companies
* Businesses definitely want to control the AI they're using (especially with RAGs of their own data) instead of just throwing it at their LLM vendor and hoping for the best
People on HN are fond of asserting that their own POV is the only one. Imagine that there is such a thing as a person in charge of choosing technologies for organizations, and that you're such a person. That's who this is for.
The Get Started button links to a contact form. That's unexpected.
I looked for the source code repository and thanks to somebody here that hinted at it as a Thunderbird project, I found [1]. That's a better Get Started page.
What's with the odd name? Apple already has a 15 year-old product called Thunderbolt. Mozilla already has a similarly-named but totally-different product called Thunderbird.
Wow HN really does have a problem with commenting on anything to do with Mozilla.
Anyway, awesome to see this from the team inside Mozilla — hope this can become a new revenue stream over the long term.
Really excited to see some tight integration with Firefox and Thunderbird in the future.
People are going to hate this, but if someday Mozilla expands to being a productivity suite I’d be pretty happy to give them my money. ProtonMail is doing it and I trust them as well.
I immediately thought "oh, the email client? It's AI now?" Then I realized this is Thunderbolt, not Thunderbird. Kind of an odd choice by Mozilla to have two products with such similar names.
It seems like all the model inference is external APIs? So why is the marketing claiming "Self-host on your infrastructure or let us help you deploy. Your data never leaves your control."
For anyone reading this that has worked on the launch of this new product (or the many others of their ilk throughout the years) under the various Mozilla orgs, I mean no disrespect, however I feel it's important to not mince words these days..
I implore ANYONE at Mozilla org to please, please stop working on projects distracting from the complex and necessary work of browser and web standards stewardship. That alone should be the very reason for your continued existence if you have any. Focus on anything outside that purview will lead to the furthering of the, already painful and readily apparent, stagnation of your browser and our standards bodies as entities distinct from corporations.
Ditching any direct financial ties to Google or any other browser vendor is both important and necessary at this point, as this clearly represents a conflict of interest in your overall mission.
The web as a platform should belong to us all, not just the few corporate leaders of the day. I've watched in real time, saddened by the persistent errosion of our commons that is the web. I see it becoming nothing more than a corporate playground should trends continue, if it's not already too late. There may have been a time when your mission took precident over product launches of seemingly unrelated domains, but that is not what Ii observing today.
I think I speak for many in the community in these regards (please correct me if not the case.)
I thought Mozilla was going to join the Thunderbolt standard and/or making some tool for it until I clicked the link haha. Very interesting name choice
So this is only for organizations and not for individuals? The Get Started button goes to a form where it wants to know how they can help your organization. I didn’t see any other link to the source code or documentation. If whoever created this site sees this comment, please clear up the above questions and observations.
Some confusion I see here is lots of people seem to not know that MZLA who makes Thunderbird and Mozilla Corporation who make firefox are separate entities in the Mozilla Foundation umbrella. This Thunderbolt is a MZLA product... so ya
This was the MOST confusing release I've seen in years.
Okay, it took me some time that the mail client is called "ThunderBIRD", not the BOLT. Not that I've used it much. But why the logo in github still shows TunderBIRD?
It looks like Mozilla is trying to catch the band wagon for no particular reason. They don't need it AT ALL. But they just jumped in along for a ride.
Chrome on Linux is ~1.47 times faster than Firefox on the Jetstream 3 benchmark as recently reported by Phoronix[0]. That's how we want you to spend the money Mozilla, keeping up with your well-funded rival Google, and making it so we don't end up with a browser monoculture. These sorts of distractions just piss me off, and are not part of your core mission.
Yesterday I actually read the docs on Open WebUI. It’s pretty impressive all the features it supports. I will give thunderbolt a look but I’m seriously considering doubling down on Open WebUI. The only thing I don’t like about their features are that tools and functions can’t be offloaded to external compute, it runs on the same machine.
Lots of negative posts here, who presume to speak for others. I, for one, welcome new entrants especially since they're under the Mozilla umbrella. This client could use the passwords and cookies stored in Firefox. And I'd trust it too, unlike other clients.
Someone explain to me why this product is unique. If Mozilla never came out with it, does that mean businesses are stuck with using cloud-based AI? C'mon. There's a lot of products that already offer local-AI. What am I missing?
Is it just me or is this really bad copy? The only clue as to what this is on the landing page is the background of the product image. And I also have to sign up to find out anything else about it.
Could Mozilla hand over firefox to a new team please? It is clear they are wasting time and energy on things nobody wanted - who wants Mozilla-AI please? I mean, seriously?
For people who don't think Mozilla wants to make firefox competitive
again; and for those who also don't think ladybird will become a
viable alternative one day (that's for the future, I have no crystal
ball, I am just pointing at one possibility here). Perhaps we could
get more momentum when someone else other than Mozilla handles firefox.

Also Thunderbolt is too similar to Thunderbird, really got me puzzled for a sec.

At a glance it looks identical to Mozilla Thunderbird, but has nothing in common.
And then of course it's also the same as a well-known hardware interface.
I know it's hard to come up with names and pretty much everything is used by something else, but this seems particularly bad.
Also, my impression is: yay another AI front-end. What does this one differently that the other thirteen in a dozen don't?

Why not "Phyrefox"?
They are so incompetent, they could not even come up with a name sufficiently different from their own product.

Like, seriously, this is like calling your AI model NVME or Northbridge or something. Insanity.

"Ah, of course it is."
Just keep making a decent browser and stop getting distracted on shit.
