Firefox cannot play media in these websites: - Spotify Web: redirects me to https://support.spotify.com/us/using_spotify/system_settings/enable-the-spotify-web-player/ (DRM is already enabled) - Twitch: error #4000 - Youtube: Some videos work, others give me the message "Your browser does not currently recognize any of the video formats available" - Twitter: "The media could not be played" Things i have tried: Going into safe mode, unable hardware acceleration, setting media.me to true (already enabled). Nothing works. Would appreciate any help
