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.
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.
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.
