I'm running Mac OS 10.6.8, have upgraded to the latest version of Flash Player, and Youtube videos will not play on Firefox 5.0. They will play on Safari. I think it stopped working when I upgraded to Firefox 5.

I was having this problem too. It is simple for Mac - clear the cache. Go to Firefox preferences, network and clear the cache. It should work then...it did for me.
