While I know Google intentionally tries to hobble its competition by making their sites run like shit on other browsers, I just can't get Youtube to play nice with Firefox. Some videos will play, but then others will just be like "playback error" fuck you. I've looked through what I can find online and nothing works, just some videos don't play, even in safe mode. Works fine in Edge and Chrome though.
Yeah I immensely dislike both the ios and android versions of Firefox. I still use them becuase having the same browser allows for syncing, history, bookmarks etc.
