Can't play Youtube videos on Firefox only
YouTube works in all other browsers. I have restarted Firefox, uninstalled it and reinstalled fresh, nothing seems to work. Disabling addons does nothing. When I go to watch a video, I press the play button, the video loads sluggishly, and when loading is finished, before the video starts, I get "An error occured. Please try again later. (Playback ID: _______)". Vimeo works fine, but some news sites have the same issue. I have also tried just signing out of YouTube, and that does not work either.
