What could be causing Youtube to stop working in Firefox, giving just a black box instead of a video?

Whenever I try to view any video on Youtube in Firefox, I get an empty black box instead of a video. There are no buttons etc, nothing at all. If I right click, a grey box appears with "About Flash..." and "movie not loaded".

Youtube works fine in Internet Explorer, and I've tried uninstalling and reinstalling Flash and Shockwave. I'm on a laptop running Windows 7 Home Premium, SP1, 32 bit, and Firefox 5.0.

Any ideas?

Try clearing the Cache in Firefox.

Tools-> Clear Recent History -> [v] Cache

or Tools->Options->Advanced->Network -> Offline storage -> [Clear Now]

Youtube may have made some changes recently. Clear the Youtube cookie and refresh page if above does not do it.
