What is actually your problem with Android FF? I use it every day on my phone.
Yes, it’s not as snappy as Chrome, but besides that everything works perfectly. In addition to that: Fully fledged ad-blocker like on desktop, one big reason why I no longer use Chrome on my phone.
You can swear on the internet. Violence? Gore? No problem!
A bad word? Son of a removed, we’re all going to die.
Edit: Wtf, there is a swear filter? Fuck.
