You have probably seen (Google) a number of pages that detail this and similar errors, which some say is a site issue, others a FF bug (FF in some systems does not play well with YT)
Finally, if you frequent tech forums, you have no doubt seen posts that raise an issue that you do not experience even though you have a similar system. For example, I run Win7 Pro x64, FF 3.6.3, Flash 10.0.45.2 and have no difficulty with YT. Why? Who knows other than to say , "Well, Dynamite140 must have some system difference from Monk, a difference that, in some way, conflicts with FF/YT - assuming both apps are installed properly and current in both machines."
Since IE and FF handle Flash differently (ActiveX v. plugin) you cannot compare the two by saying, "Gee, I can view YT in IE but not FF."
All of this is a very verbose way of saying, I'm stumped. Maybe others can pipe in and I will keep an eye out should I see something on the Net.
