Tor browser removing various Firefox AI features

Mozilla has a staff of around 1700 employees in USA, but it has 1000+ volunteers. Are those volunteers getting a fair share of the profits of this non-profit company? If not, why not?

And even with all that half a billion dollars of revenue every year, why is Mozilla Firefox have a barely ~2% market share?

OK, Let's talk basics and real stuff..

Why has Firefox failed or deliberately delayed to give basic features for years that its major competitors have had for years?

Why is a company getting millions of dollars (from its biggest competitor) for doing the bare minimum (or is that a quid pro quo deal between them)? "Too little, too late" seems to be the norm at Firefox and Mozilla in past few years.

e.g., Firefox users have been demanding Tab Grouping for years (and the other major browsers have had Tab Grouping feature for years), but it was only in April 2025 that Mozilla finally gave that basic feature in Firefox: https://blog.mozilla.org/en/firefox/tab-groups-community/

Or is that the implicit deal between Google and Mozilla. "Hey puppet, if you want the carrot, then just keep your head down, and just tick along doing barely anything new, and let me control the world as I see fit."

I'm genuinely wondering: if any other decent non-Chromium FOSS browser got half a billion dollars every year, would it give some tough competition to Chrome and Safari?

I have been satisfied with moving to Zen, a Firefox fork that behaves like the late Arc browser

Mozilla maintains 32 million lines of code, roughly the same amount as Chromium, with by some estimates, less than a tenth of the resources Google dedicates to Chrome. That return on investment spans everything from leading on development of major new web standards, e.g. WebAssembly, WebRTC, DNS over HTTPs, limiting cookies, profile sandboxing. It also includes Rust, key to their major "Quantum" project which by itself was a monumental achievement which rebuilt the browser on a stable, secure, memory safe foundation. Even Chrome is now starting to use Rust, Mozilla's language, for parts of its browser.

They have a rapid patch cadence for security fixes, and their browser is the heart of an ecosystem including Tor, Waterfox, LiberWolf, Mull, and others for niche, hardened or performance tuned variations that depend on Gecko. Tor, in particular, is relied on to get around censorship in parts of the world that try to control internet traffic.

And there's the monopoly issue, which is that if we lost Firefox, every active browser engine would be owned by two trillion dollar platform companies, Google and Apple, who could write the rules of the internet on their own. Which includes, among other things, trying to dismantle ad blockers and lock you into their ecosystems.

The totality of its return on investment across security, open standards and browser independence has been irreplaceable, and overlooking that because they didn't roll out a tab feature fast enough is mind-boggling lack of comprehension of the full scale of what Mozilla produces from beginning to end.
