Video won't play in firefox

more options

I've downloaded the latest versions of firefox and flash, but can't watch youtube or any other online video. Youtube gives an error message. It used to just play automatically, but now I have to click the play button, then error appears. I've also update quicktime and realplayer recently as well. I can watch with IE9 no problem and I don't know what the problem is. Any help is appreciated!
