Actually it happens with any videos with flash player in any website. By the way to be clear I'm using Firefox Developer Edition.

Cheers!

This also seems to occur on Windows 7 with the latest nightly (maybe Windows specific though?)

It has been going on for less than a week I believe but I'm not positive since it was initially quite subtle and seems to get worse as time goes on. Meaning it would have been missed on a lot of the small videos I tend to find.
