Reporter: Can you help give us more information regarding the issue you are seeing? URLs for videos would be helpful about:support graphics information platform information (Win/Mac/Linux) Is it happening on all videos or only certain ones? Thanks!
berkay3322: If you open about:config in the URL bar, and right click and add a boolean pref media.fmp4.demux-skip and set it to false, does the problem go away?

I have the same problem after updating to FF 36 b6. The audio and video will go out of sync after 5 minutes. I also tried 36b9 and it had the same problem. I'm back on 36b4 and it is working ok. Mind that I have just made a fresh install on windows.
