Firefox can play videos in safe mode but not in normal mode. I have disabled all the plugins, reset the browser but problem still continues.

Everything works fine about the videos when I use in safe mode but when I switch to normal mode, in most of the websites (e.g. Vimeo) the videos cannot be played. I have reset the browser so currently I have no add-ons, I downgraded the Adobe Flash Player to 10.3 still problem is not solved.

Since flash player works fine in safe mode but node in normal mode, I doubt this problem is related to Firefox not Adobe Flash Player.

Hi burakb,

If you have RealPlayer installed - update it, also, Turn off hardware acceleration and "disable the hardware acceleration" in the Flash Player too :

Thank you ideato. Disabling hardware acceleration solves my problem. Now everything works fine. But is it going to decrease the performance of firefox since I will not use hardware acceleration?

Hardware acceleration is using GPU when it’s possible to help page-drawing operations faster, but the increase of performance is negligible (if working well).

see for more info:

EDIT : same in flash player http://en.wikipedia.org/wiki/Hardware_acceleration
