I know it’s not helpful but I don’t have any of these problems. Very much plug and play for me.

Don’t know much about this but now I’m curious. What happened to Mozilla and why do you recommend Librewolf as an alternative?

Yes that fixed it, thank you. Feeling a bit stupid for not having the idea to check for updates myself…

Got “It looks like you’re outside of the United States. YouTube TV is only available in the US.” after logging in. Didn’t know the US had their own version :D

I found the problem, apparently something in Firefox broke and disabled all my plugins because they can’t be verified, including “YouTube for TV”. Can’t even install new plugins right now and sometimes having Firefox open just randomly crashes my steamdeck.
