You tube video will not play. Shows a black screen. You tube will work on IE. This is a recent event as I was just watching YouTube videos last week.

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.
