Dear Firefox Team,
Thanks for making such a wonderful browser...
I too have the same problem. It just run any videos just fine with the previous beta 6. I'm running mac os x 10.6.4 with 64 bits kernel enabled.
Make sure that you have the latest version of the Flash Player (10.1 r102).
The problem is solved after I'm upgrading my OS X to 10.6.5. I wonder whether the upgrade or the restart that cure the problem since I haven't restart it for a month, ;).
I'm having this problem as well. I'm fully updated to OSX 10.6.5, fully updated to flash 10.1.102.64, and running beta 7. I just get a black box when I visit sites like Youtube and no video or image at all. Every site I've visited on this machine that uses flash seems to have a problem (for example, on nvidia.com, the "Choose your location" flash intro doesn't play).
