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.

It's a crazy crowded space. Any entry into this field looks like a "me too" product driven by FOMO instead of being motivated by (a) serving customer needs, (b) serving social needs, or (c) making money. (All of which are fine with me) It will get 0.5% market share -- and I'm supposed to get excited?

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.

I love them. They are not mandatory, only shady websites that rather sell users information than providing a barely functional homepage. Yes the popups suck, but I'm very happy that this exposes the behavior and priorities of the industry.

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.

The "Announcing Thunderbolt" page actually makes this clear, the submitted URL does not. Maybe the submission should be changed to this URL instead:

Can the team please use that money on making thunderbird look like the nice UI mockups that were published that don't look anything like thunderbird.

drzaiusx11 6 hours ago | parent | prev | next [-]

I see no reason this product should exist even under the Thunderbird umbrella, especially if ANY resources under ANY Mozilla org were employed in this. This product is a distraction from their core mission in either case.

I would rather have them work on Thunderbird.

Thunderbird was literally asking for donations just a few days ago?

ryanleesipes 6 hours ago | parent | next [-]

This was built with money from an grant from Mozilla. See the bottom of this page: https://www.thunderbolt.io/announcing-thunderbolt

Took me a bit to find, so here's it quoted:

> Thunderbolt is funded through a dedicated investment from Mozilla and is being developed by a separate team focused on enterprise AI products, distinct from Thunderbird’s donation-supported consumer product work.

philipallstar 4 hours ago | parent | prev [-]

Mozilla gave Mozilla a grant, so that's all there is to it I suppose.

Wolfrich 7 hours ago | parent | prev | next [-]

it is a patreon style thing, they are donation funded. I think the poster is saying that they arent being frivolous with their money like some people have a bad taste about firefox

eipi10_hn 7 hours ago | parent | prev [-]

And?

bakugo 6 hours ago | parent [-]

And they're taking money donated towards Thunderbird development and spending it on random unrelated AI slop ideas that nobody asked for. You really don't see anything wrong with that?

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?

eipi10_hn 6 hours ago | parent | next [-]

Why do you know that nobody asks for? Are you in the team?

rothific 6 hours ago | parent | prev [-]

Stop spreading misinformation, it's funded by grant money https://github.com/thunderbird/thunderbolt/blob/main/docs/fa...

bakugo 6 hours ago | parent [-]

Ah yes, a grant from Mozilla, to Mozilla.

It goes to show that Mozilla(s) could, if they really wanted, restructure Mozilla Corporation / Foundation.

(edit - to allow users to fund Firefox, allowing us to better sleep at night, and to align our incentives)

>Thunderbird is revenue positive

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?

Thunderbird currently runs entirely on donations, even though they have paid products in the pipeline.

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].

Thanks, that's helpful. This says about ~70% of the money was paid to employees, ~10% infra costs, the other ~20% various other fees and smaller expenses.

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.

ryanleesipes 6 hours ago | parent | prev | next [-]

No, this was built with money from an grant from Mozilla.

No what? That doesn't contradict their comment about Thunderbird.

Wait what, they took donations to pay a team to build a mail client and had them build an AI thing instead? Or have I got that wrong.

ryanleesipes 6 hours ago | parent | next [-]

No, this was built with money from an grant from Mozilla.

I don’t know why you’re downvoting, it’s a fair question based on the above comments.

monooso 6 hours ago | parent | prev | next [-]

Just for clarity, you do mean Thunderbird (the email client), not Thunderbolt (this new AI client)?

tadfisher 4 hours ago | parent [-]

Thunderbird (the email client) was spun off from Mozilla Corporation into a new for-profit company called MZLA Technologies. Both corps are still subsidiaries of the Mozilla Foundation. Thunderbolt is a new product from the MZLA Technologies team.

I am a happy Thunderbird user. But when I see such reorganizing and deliberately confusing naming, I assume that there is somewhere intent to deceive.

What does “revenue positive” even mean?

It doesn’t mean profitable, it doesn’t mean cash flow positive.

Are you just trying to say their revenue is greater than zero?

BoredPositron 2 hours ago | parent | prev | next [-]

Hu... Revenue positive just last week that had a pretty dire sounding call for donations ala make sure thunderbird can survive...

bakugo 7 hours ago | parent | prev [-]

> 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?

rothific 6 hours ago | parent | next [-]

I think that wasn't phrased well- it's "revenue" positive meaning donation money covers more than the expenses

anildash 5 hours ago | parent [-]

That’s literally what the phrase means. Can’t help if people don’t know what words mean. It was phrased fine, it wasn’t _read_ well.

rothific 4 hours ago | parent [-]

Fair point :)

godelski 6 hours ago | parent | prev [-]

You think that just because the software can be downloaded for free means the developers shouldn't get paid for their work?
