Youtube videos won't load on Firefox (I get a black screen) but will load on IE. Other Flash-based websites work normally.

I've been using Youtube on Firefox normally for years, but now the videos are only a black screen where the video should be, with nothing else (no play button or anything). They load normally on IE. I tried thinking of something I could have done to provoke this, and the only things I did recently was update Flash and Java (in that order). YT still worked after the Flash update. I tried reinstalling Java but it didn't work. I didn't reinstall Flash because it works fine on other websites so I don't think this is the problem. I also tried disabling hardware acceleration on Flash but it doesn't solve it. Interestingly, the Youtube test video in this page does work. I also tried whitelisting Youtube on Adblock and disabling Greasemonkey, to no avail. I have run out of good ideas to try. Thanks to whoever can help!

edit: Hmm, I changed http:// for https:// in the address bar and the video will load. However I don't want to type this every time.

edit2: They suddenly are working again without me having done anything. Guess it was Youtube's issue.

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.

Interestingly, the videos are now working normally again, and I didn't do anything! They just came back on their own...

Youtube works OK for me on Chrome, Opera, Flock and IE8 but not Firefox. I have tried reloading / updating Flash etc but to no avail. Usually it will start to play a video and then within a fraction of a second the control bar will disappear and the black screen covers everything and sound and vision are terminated. The hpps dodge does not work either.
