mp4 problem in Firefox v37.0.2 Windows 8.1
I'm using Firefox with 4 profiles. One of them doesn't work mp4. What could be the problem? When I open mp4 http://www.quirksmode.org/html5/videos/big_buck_bunny.mp4 it says "Video can't be played because the file is corrupted.".

After I compare prefs.js files of both profiles I saw that "media.windows-media-foundation.enabled" was false. I opened about:config and reset "media.windows-media-foundation.enabled". After restarting Firefox http://www.quirksmode.org/html5/videos/big_buck_bunny.mp4 has been working perfectly.
