I recently started having a problem using firefox with youtube. I installed the Tamper Data add-on and restarted. After I restarted no youtube videos would load. They just sit with a black screen. I've tried clearing all cookies and restarting firefox. I've also tried disabling the Tamper Data extension but it does nothing. I updated adobe flash player as well. This does not happen on any other flash-based websites. All youtube videos work perfectly in IE and chrome. Thanks.

I downloaded firefox 4 beta 11 and it seems to work fine. Apparently it has something to do with the old version not supporting some codec used with HTML5 on youtube.
