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

I believe that's just an option between using the libvpx bundled with firefox
as recommended by mozilla, or using the system libvpx.

versions are actually unstable in any way, and if I google "youtube html5
firefox" I find that "Google will enforce the use of HTML5 video on YouTube for
all Firefox users who use Firefox 33 or newer", "FYI: Firefox 35 uses the
HTML5 video player in Youtube by default" and "Firefox 37 Released With Native
HTML5 YouTube Playback"
Firefox 37 still uses the flash player for youtube. It will fallback on HTML5
if the flash player crashes. There's an update on that page that the change has
been delayed.
