15 codec, but Gentoo's USE flag and package descriptions have always been rubbish.

20 I believe that option is just a choice between using the libvpx bundled with
21 firefox (as recommended by mozilla) and using the system wide libvpx.

26 versions are actually unstable in any way, and if I google "youtube html5
27 firefox" I find that "Google will enforce the use of HTML5 video on YouTube for
28 all Firefox users who use Firefox 33 or newer", "FYI: Firefox 35 uses the
29 HTML5 video player in Youtube by default" and "Firefox 37 Released With Native
30 HTML5 YouTube Playback"

32 I'm using firefox 37 and it has always used the flash player. It has fallen back
33 on HTML5 a few times because the flash plugin crashed. It uses flash even if I
34 open a private session (no cookies) or even if I move the ~/.mozilla
35 directory, It also says on that page that the option to switch between HTML5
36 and Flash was removed on firefox 33 and I still have it so they must have
37 changed their mind.
