What kind of Pi? Can you watch UHD without issues on it?

No. Also uninstalled the app and use Invidious.

Yeah. Sounds like Firefox is not the real issue here.

Amen. I can remember the “this site is best viewed on Internet Explorer” badges. Let’s not go down that route again.

I have zero issues with FF, apart from Teams but fortunately I rarely have to use that shitty app.

What sites do you have issues with if I may ask?

See if you can find the chinese backdoor on it.

DDG. I used Searxng selfhosted for a while but it was a bit too slow with its results.

Is there anything like LibreTube for iOS?
