What makes you disqualify Firefox from being a "proper open source browser"?
> Between mid-December 2009 and February 2010, Firefox 3.5 was the most popular browser (when counting individual browser versions) according to StatCounter, and as of February 2010 was one of the top 3 browser versions according to Net Applications. Both milestones involved passing Internet Explorer 7, which previously held the No. 1 and No. 3 spots in popularity according to StatCounter and Net Applications, respectively - https://en.wikipedia.org/wiki/Firefox_3.5
Then Chrome appeared and flattened both IE and Firefox.
There's 5 billion people on the internet. 5% of that is 250 million.
Some companies would kill for user numbers like that. Hell, some would slaughter entire villages.
That's certainly not true. Unless Red Hat, MongoDB, Chef, etc. are not open source.
While I love to believe that the FOSS world is an anarchist utopia that believes in wellbeing for all, I think there are plenty of profit driven people there. They just don't sell access to the code/software.
In reality people espouse this opinion then continue using Chrome or Chromium browsers.

- June 2024. Mozilla acquires Anonym, an ad metrics firm.
- July 2024. Mozilla adds Privacy-Preserving Attribution (PPA), feature is enabled by default. Developed in cooperation with Meta (Facebook).
- Feb 2025. Mozilla updates its Privacy FAQ and TOS. "does not sell data about you." becomes "... in the way that most people think about it".
1. You could (however, I doubt the effectiveness) use something like brave which tries to randomize your fingerprint.
2. You could "blend in with the crowd" and use tor.
(debian, latest tor browser 14.5.3, no modifications)
I've always used it inside of whonix, and when I tested it, it seemed like everything was fine.
When you disable js you need to do so by setting tor to Safest.
The font list should be spoofed by tor?
Anyway, you can fix all of that just by using whonix and setting tor to safest.
That's... not accurate at all. Firefox was extremely popular at one point, and completely ate the lunch of everything else out there. (And then Google used anticompetitive practices to squash it, but that came later.)
Not exactly. Apple happened.
Every "web designer" had to work on a macbook to be different like every one else. And firefox had dismal performances on those macbooks so said designers turned to the only browser with good tools and good enough performances: Chrome.
Next time you're told "performances don't matter", remember how it can be a differentiating feature and could cost you your market share.
Sorry? Why? I must’ve missed that memo :)
To be honest it's still better (at least if you ignore the manifest V3 nonsense).
Why on earth are we, in 2025, still sending overly detailed User Agent strings? Mozilla/5.0 (X11; Linux x86_64; rv:139.0) Gecko/20100101 Firefox/139.0 .... There are zero legitimate reasons for websites to know I'm running X11 on x86_64 Linux. Zero.
Why are Refer(r)ers still on by default?
Why can JS be used to enumerate the list of fonts I have installed on my system?
We need way more granular permission controls, and more sensible defaults. There are plugins to achieve this, but that's a big hassle.
Most browsers with fingerprint protections will for example introduce random noise in graphics and audio APIs.
> your browser shares a surprising amount of information, like your screen resolution, time zone, device model and more. When combined, these details create a “fingerprint” that’s often unique to your browser. Unlike cookies — which users can delete or block — fingerprinting is much harder to detect or prevent.
Ironically, the more fine tuned and hardened your device, OS, and browser are for security and privacy, the worse your fingerprint liability becomes.
more idle thoughts - it's strange and disappointing that in the vast space and history of FOSS tools, a proper open source browser never took off. I suppose monopolizing from the start was too lucrative to let it be free. Yet there really is little recourse for privacy enthusiasts. I've entertained the idea of using my own scraper, so I can access the web offline, though seems like more trouble than its worth.
