I’ve exclusively used firefox to watch youtube on Arch and Ubuntu for years, never had a problem so far for what it’s worth. I keep a laptop in the livingroom with Arch specifically to have adblocking and piping the video out to the TV. The youtube apps are terrible on the Roku last I remember, haven’t tried it in forever but I think the main reason was I didn’t want to see ads anymore.
