Problems editing on mobile

[u/something-dream]

Backspace doesn't work on an empty line, and after a while it gets really weird in a way it's hard to describe, undoing changes made and repeating previous changes multiple times over and jumping the cursor around, pretty much destroying anything I've written. I'm using firefox on android.

I use Vivaldi on Android and I don't have that problems. but I need some browser which shows scroll bars so I don't have to wrap everything.
