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.

> Thunderbird is revenue positive

Is that why I'm met with a splash screen asking me to donate every time I start Thunderbird? Is this another Wikipedia situation?

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.

120k LoC of probably largely vibecoded nonsense for a window with a text box and a button that lets you send and receive some data over a HTTP API.

Their Thunderbird for iOS repo is 34k lines.

I'm so very tired.

"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 / internationalization, as one example.

Wait what ? Did you include libraries imported by NPM in this count ?

I imagine that would bump that number to milions.

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 don’t think so. I just used a public GitHub LoC counting tool directly on the repo, there are a few.

https://ghloc.vercel.app/thunderbird/thunderbolt?branch=main claims 141k and most of it is Typescript.

Curious name choice, that's clearly encumbered by other trademarks.

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.

I'm somewhat a fan of Mozilla, but their weak governance with regards to actual plans for the future, a couple of questionable partnerships, and the graveyard of products makes it hard to trust based on a 15+ year-old reputation. Would love to see where Mozilla has meaningfully contributed to the modern tech space (things we all actually use, not Mozilla versions of more popular apps/tools)

This Mozilla?[1] The company whose 85% of revenue depends on an adtech giant?

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 I may, Mozilla, you shouldn't release half-ass products that looks vibe coded like this, even the website looks like it took 30min to do with Claude

People "want" a lot of contradictory things. People "want" them to be less financially reliant on Google, while also "focusing" on a browser in a market that is entirely commoditized and subsidized by 3 of the 10 largest companies in the world - and having a wholly implementation independent browser engine when it's so massively difficult and capital intensive that even Microsoft gave up on that.

The anti-trust lawsuits with Google have Mozilla realizing they can't just be a company kept afloat by Google. Mozilla's priorities have been pretty complacent, basically just maintaining Firefox, sometimes Thunderbird, and a couple side services that have little financial incentives.

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.

This is from MZLA Technologies, so is a sister product to Thunderbird rather than Firefox.

OK, but does Thunderbird have flawless exchange support yet? Can I replace Outlook with Thunderbird for our 365 accounts? Does Thunderbird have UI that is welcoming and modern?

Does a dollar go from Marla to MZLA? Are those dollars not fungible?

I agree with you, there are 1,000 different chat apps and just one Firefox. And the world needs Firefox more than it knows.

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.

There is "only one Firefox" but Firefox exists in a market that is not just commoditized, but subsidized to the tune of billions by 3 of the 10 largest companies in the world.

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.

If this is correct and Firefox is now 2.3% opposed to Samsung Browser and Opera both at 2%… it’s pretty much over.

https://gs.statcounter.com/browser-market-share#monthly-2009...

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 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

This is a fair point. There is absolutely no way they didn’t know what Thunderbolt is, so they did this on purpose. Just rack it up to the list of obviously bad decisions that brought us here.

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

Some of us are out here still waiting for Firefox relay “premium” to launch and provide disposable mobile numbers like they do email addresses.. but product has for some reason been stuck on “join waiting list” for what feels like an absolute age.

Pocket, lol. I think the Mozilla VPN could have been OK but it was just rebranded Mulvad and they didn’t make it easy and obvious to use.

Is there a FF fork doing anything good out there?

Yikes.

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.
