Also, my impression is: yay another AI front-end. What does this one differently that the other thirteen in a dozen don't?
Mozilla's a lot more trustworthy with privacy and data, and they're unlikely to sell the project to someone who only wants to stuff it full of malware/adware/crypto stuff - or do it themselves.
Nobody I'd mention on Hacker News!
They're certainly doing better than others in this space, but their track record does not inspire confidence for anyone concerned about their privacy and data.
If you were not working with Mozilla Asian area, you know far too less. They had a browser in China that redirect to different website for profit before every connection and some affiliation. By doing so, is it privacy or not? Oh, look at Mozilla Japan volunteers, they shut everything up because things went wrong.
"I'm using Mozilla Thunderbolt."
"Huh, do you mean Thunderbird?"
"No, Thunderbolt!"
Is there a FF fork doing anything good out there?
Floorp comes with additional custom interface features, workspaces (tabs grouping) and mouse gestures. And bit better profiles feature - Mozilla decided to redo it recently which lead to some problems.
Mullvad has build in VPN, DoH and proxy as an extension, and comes with uBo and NoScript.
There's Zen browser that has a quite uncommon UI, and obscure Pale Moon that IIRC still tries to provide old XUL/XPCOM extensions - which often leads to pages rendering issues.
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.
Their Thunderbird for iOS repo is 34k lines.
I'm so very tired.
https://ghloc.vercel.app/thunderbird/thunderbolt?branch=main claims 141k and most of it is Typescript.
I just checked one old take home task in Angular I did last year and the total number of lines is over five million over 35k+ files.
"I will make loads of assumptions without checking so that I can invent reasons to get mad"
Note that about 30,000 of those lines are JSON files for localization and testing, as one example.
Especially curious because I see a whole lot of hardcoded english text in there…

Regarding "loads of assumptions," it's hard to tell how much of this is vibecoded slop (definitely non-zero looking at the commit log), but I don't think it's that outrageous to claim 87k sloc is too much for a textbox and an API wrapper.Would recommend exercise
* 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.
Is that why I'm met with a splash screen asking me to donate every time I start Thunderbird? Is this another Wikipedia situation?
Hmm, I thought the for-profit Thunderbird pro hadn't launched yet?
I know Thunderbird is for profit, but what are they profitting from without the paid service, and how much of that profit is going into this unrelated Thunderbolt AI platform, exactly?
I think a piece of software running on donations is not running off "charity". It's just a business model to not charge every user. Similar to how Twitch streamers operate, or my local theater group.
You can read how they spent money in 2024 [1].

It would be interesting to have a breakdown of what part of the Thunderbird team is working on Thunderbird, Thunderbolt, or other forms of thunder.
Surely you can agree that when you open Thunderbird and are met with requests for donations, if you chose to donate, you'd expect that money to be invested in Thunderbird development, and not 10M Claude tokens to vibe code Mozilla's latest groundbreaking AI B2B SaaS idea?
(edit - to allow users to fund Firefox, allowing us to better sleep at night, and to align our incentives)
Yes, agreed on that. I'm not sure I'm clear how this really helps that; I suppose it's a frontend that they don't have, but there are a bunch of those already.
It doesn't seem to help them control the _actual_ AI, i.e. the model, which still has to come from somewhere.
If you lived in New York City you might think there are Duane Reades coast-to-coast but there are not. If you are based in the Bay Area you see billboards that are very different from anywhere else. I'd say the viewpoint is a lot like this famous artwork
https://en.wikipedia.org/wiki/View_of_the_World_from_9th_Ave...
but maybe instead of the rest of the US being 1/5 of the vertical space it is 1/25 of the vertical space. Problem is most customers do not live in the bay area and most web browser users do not live in the bay area and most web developers do not live in the bay area. Based in the Bay Area they can hop in their cars and drive the longest 40 miles in America to get to Google and Facebook's headquarters so Mozilla is talking to those people all the time and not talking to the rest of us.
We don't get costly signalling to show they care about the rest of us, we don't even get cheap talk.
They probably think René Girard is deep because they are surrounded by people who think René Girard is deep. If Mozilla wants to be relevant and not just an also-ran it needs to "think different" like the other 99.9% -- it's not that hard if you change your location.
Really the EU needs to apologize for those damned cookie popups and invest in a privacy-first browser. Whether that is "fully fund Firefox" or "fully a fund a Firefox fork" or pick up another browser engine or start a new one.
I see the warning lights flashing: a few years back web sites that didn't work with Firefox were few and far between, this weekend I bought tickets for a comic book convention and they took my money but didn't give me a ticket because the site didn't work with Firefox. I use Firefox as my daily driver so all the projects that I work on work with Firefox; the rest of my team doesn't give a damn and if you lose me another site will become Chrome-only.
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."
I've already used up "cum" btw, so you're not allowed to name your product that.
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.
The cherry on top is that the domain is thunderbolt.IO. No other TLDs to pick from?
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.)
This reads like a kid trying to give business advice to an adult. “You could do THIS, then THIS, it would also be cool if you did THAT but please don’t do THAT!!”
C’mon now.
The fact that is being run like one, albeit poorly is exactly the problem.
I don't think you realize the irony in calling my post childish here. "C'mon" I guess?

What's wrong with Firefox? There are several things Firefox does that it's annoying to live without in other browsers (video pop-outs, competent ad blocking, etc). Is there some core feature that's missing? I'm subjected to Edge at work and I couldn't tell you a single thing it does that I'd want FF to do.
> and our standards bodies as entities distinct from corporations
Ok, I buy that.
As for HEVC, that particular licensing trash fire continues to burn bright. VVC had an opportunity to learn from the situation, and decided what they really wanted was a trash fire that burned even brighter.
So, we might be stuck with H264 for a little bit.
That number can be down to any number of different factors on reddit itself. Having an autoplay video running, etc.
Debugging the extension on Chrome, it works great. On Firefox, it is nearly impossible. There are a litany of compatibility issues that make it "different" than Chrome, despite the extension being very much standards based. It is really frustrating and makes me dread getting bug reports.
To be fair, Safari is even worse and I haven't even touched Edge yet.
As much as I'd love to have options in the marketplace, standards based compatibility between offerings should be a top line requirement.
It seems like every thread talking about Firefox always has someone asking that question, so if you search back you should find plenty of reasons. Unfortunately, it’s been my observation that valid and polite criticisms always get downvoted. I don’t understand why. It’s not like downvotes are going to make the problems disappear.
Most of us would like Firefox to succeed, and it’s none of our faults that Mozilla is constantly neglecting it and going off on wild goose projects which get promptly abandoned.
I see Firefox now as the new Opera, a technically good browser making dubious extensions that no one asked for until it dies a slow, spiraling death. My plea is simply to not go down that road any further...
Blocks ads Multi account containers Dev tools very good
I never notice that it is in any way slow, except for those sites that need infinity cpu on any browser, like jira.
What specifically is the issue? To my mind it quietly just gets on with things.
Doesn’t this have to be done under another name to prevent massive company-killing pushback?
Just keep making a decent browser and stop getting distracted on shit.

It looks like they might want to get into hosting/selling services to users on this.
From the FAQ:
> Is there going to be a hosted version if I don't want to deploy it myself? > Yes, we are planning to launch Thunderbolt for regular users but we do not have a release date yet.

The world may need Firefox but it's funny how people complain about Mozilla's dependence on Google while also complaining about every attempt to become more financially independent from Google.

As a former Netscape user… I think it’s almost masochistic to remain on Firefox as it’s rewarding a company that mismanaged its only product into the ground. And for what? What is the amazing thing Mozilla did at the expense of Firefox and donating the direction of internet technologies to Google?
The executives got to attend a bunch of fancy gallows, and Pat themselves on the back?

I want them to go cap-in-hand to other countries and say "if you don't fund us then you are letting the US and surveillance capitalism get between your citizens and their government" and "do you really know what Chrome is doing with your data?"
I don't want to pretend they are simply part of a browser marketplace, but rather have them realize they are part of a civil rights effort, with powerful non-market forces they can ally with.
And I want those governments to commit to progressive enhancement guidelines like https://www.gov.uk/service-manual/technology/using-progressi... so new alternatives like Ladybird can start, and further require their agencies to test on a Firefox branch with no AI, no location tracking, full ad-blocking, etc. because while the market is free to ignore certain non-profitable users, a government should not be allowed to ignore some of its citizens.
I don't see a contradiction there.

Investing on AI is not going to make them less financially reliant on Google.

The current state of Mozilla is pretty odd since they rebranded to make it more apparent they're a non-profit, while also attempting to become more profitable pushing out new products and services.
