MP4 Video is not playing in Firefox 35.0.1
Some of my MP4 videos are not playing in Firefox. They worked fine last week. Now I get the "Video can't be played because the file is corrupt" message. The video works fine in IE, Chrome, Opera, Safari

I'm using Firefox with 4 profiles. One of them had problem to work mp4. 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.

Forgot to post a link to the video:
No problems here with both those MP4 files in the built-in HTML5 media player.
Make sure that your security software isn't causing this problem. Boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.
I see that sudogo has created a new thread, so lets continue there.

I'm able to reproduce the issue with the MP4 gdws1_15.mp4. See bug https://bugzilla.mozilla.org/show_bug.cgi?id=1133504
If you have problems with current Shockwave Flash plugin versions then check this:
- see if there are updates for your graphics drive drivers
https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration
- disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)

Read the bug report, it's a bug in Firefox and it will be fixed in FF37+.
