Thank you for your reply but i have already tried that and didn't work. I did some more research and the problem is plugin-cointainer.exe when i stop this process firefox unfreezes. So the problem is with the flash plugin.

I Manually uninstalled the flash plugin and it seems to work without the plugin. It seems youtube is now working with HTML5. Could that be the problem when I have flash installed -> that firefox doesn't know how to combine or to use each one of the two(html5 & flash)?
