Yet I pick a Chromium based browser because Firefox is awfully anti-user. I still can't load extensions that are not Mozilla-approved, a major deal breaker for me. Then there's the "news" (ragebait slop) on the new tab screen by default, almost like I'm using MS Edge, and also the many sponsored & "suggested" (read: sponsored) links by default in new tab and the address bar as well.
The only acceptable Gecko-based browser I know of right now is Zen, which is great but still in beta. And Tor & Mullvad Browser are good for private one-time sessions.
We need competition for a free and open internet, I fully agree. Mozilla is far from a decent champion for that cause. I'm far more excited at what Ladybird has to offer.
Extensions in Firefox are required to be signed by Mozilla. If you make your own build of an open-source extension, it will not load. The setting to disable this check only works in Developer Edition, ESR and Nightly builds.
Firefox nightly is pretty darn stable, though I'm not sure if there's any security issues with it. I use it for both mobile and desktop, and have for the past 5~10 years and haven't had any issues that weren't fixed by immediately downloading a fresh build (this happened twice) or were caused by me performing unsupported/insane actions (transferring browser profiles (indexeddb) on mobile via CLI commands using remote devtools).
I've got one buggy device, but I suspect corruption due to the error message and I'm more interested in saving the unsyncable data I've got on that profile than I am in trying to fix it by clearing data.
Sponsor stuff that you can just turn off (Firefox) vs. Selling out your privacy directly (chromium with worse fingerprinting protection) and indirectly (Google browser monopoly).
