I sorted out my add-on problem and youtube works fine and dandy. If you disable all of your add-ons and it still doesn't work you will either need to re-install FF, or move to a different browser. At least you have some choices now if you don't want to use IE.
I've yet to come across a website that that doesn't work fine on FF, other than youtube, which I sorted out in the end. But on a few Mozilla forums there are a fair number of people who have the youtube problem in particular. There are a few possible solutions on those forums.
