Eh. Firefox is fine.
The only FF fork I’ve ever used for some time is Cachy Browser, as it shipped with my distro and was ostensibly amore optimized. But even they depreciated it in lieu of vanilla Firefox.
And Firefox gets faster security patches anyway.
I’m more interested in Chrome forks because it’s Google spyware. And, as much as I don’t like it, I find Chromium-based browser to be faster. That doesn’t matter so much on desktop, but the difference is pretty dramatic on Android.








No Linux client for that either, though it seems to be planned.
