Comment (by gk):

 Today a user came into #tor and said that some videos are not playing
 anymore in Tor Browser 8 which played in Tor Browser 7.5.6. After some
 debugging and back and forth it turned out that the Linux user agent is
 the reason for that: the spoofed one allows to watch the videos while in
 the current situation Linux users only get essentially "Sorry, video
 format can't get played". So, *not* spoofing is actually breaking things
 for Linux users. I guess that's a further argument for fixing this issue.
