I came from a ~10 year old phone so FF5 was a big upgrade. Battery lasts the work day (may go from 80% to ~50% or ~30% mostly playing bluetooth audio for like 4 hours on and off). Fairphone uses some industrial chip instead of a mobile one - so it uses more power but they say it can get much longer updates than other phones. I usually have the screen set to 60Hz to save power, but a cheeky 120Hz session feels great. One bug is I can’t charge it in power save mode.
I got standard Android but replaced the proprietary store/apps (updates still requires Google Pain Store). I planned to try out an Android fork later but that’s was not as easy as I had naively thought. [Requires an SDK binary that come with non-free license and 3rd party guides to build it myself were rather dead].
I not aware it could run non-android OS - do you have exp installing a Linux phone OS? How did you find that? I’ll have to look into FF5 compatibility.
Small teams are unable to take web browsers far in another direction as browsers have recklessly grown to one of the largest and most complicated software. Browsers do not follow the “do one thing well” philosophy, to the extreme.
Most functional parts of a browser (text reader, video player) are thankfully resistant to enshitification. That is if they are free (libre), permitting a fork.
