I use Firefox on PC and I’m happy with it there. But on my phone Firefox isn’t great. Scrolling and zooming is pretty choppy, not excessively but it shouldn’t be choppy at all.
Edit: after posting this I tried using Firefox again for a while. I take back the “excessively” part. It is distractingly slow, there’s no reason for it to be that bad
What adblocker are you using? I’m also in Austria but haven’t got it
