Just installed Firefox 5 and videos from Youtube are not showing! Instead i get a black box in the video area and no other activity. Using latest flash version.
With Firefox 4 everything worked fine. Also in IE everything works fine too. Systems runs Windows 7 x64 Ultimate. At any other site videos are showing fine, only at Youtube i have the problem.

This problem is not a Firefox problem, but a YouTube problem.
See this thread at YouTube's official support forum:

Just updated FF to 5.0.1. Same problem using win7 Ult64. Works fine in FF/Ubuntu and Opera under Win7.
