I honestly gave it a go, and I liked that I could run ad blocking, but the constant crashing and poor website rendering shoved me back to chrome on mobile a couple weeks ago. I'd rather deal with ads and have the browser be stable apparently.
What's not working? Most broken websites are fixed by having it flag itself as chrome mobile, which is telling that your falling for what Google wants right now. And what crashes are you getting? I get one no more than once a week if that and I have over 100 tabs open
Wait, you guys get crashes on Firefox Mobile? Like legit, I was using Firefox for months, in fact, nearly a year, with over 100 tabs opened constantly (it showed up as an Infinity sign, lol) and I don't remember ever having Firefox crash on me. That's unusual.
I didn't have a list of every website that screwed up, but when one did I'd have to close the tab and reopen and it'd work, which sucks when you are actually navigating the Internet.
It wasn't that the stuff wouldn't load on Firefox it's that it would freeze and need to be dumped and retried. This happened very frequently.
Actual crashes were almost daily for me (with maybe 5 open tabs running on a Samsung flip 4, so pretty decent hardware)
Which sucks because I'd like Firefox to work on mobile, setting aside privacy and ads, the UI is much better in general. But it's bad at being a browser.
I use it on mobile just for uBlock. As far as I know it's the only mobile browser that supports extensions. If you use their nightly version it can use any extension that you can get on desktop. The base version only supports a few extension, but uBlock is one of them.
