FireFox 18 does not work with youtube, web video

Youtube, Flash Videos do not work in Ver. 18.0.0 I have run FireFox with all add-on disabled installed new drivers for Flash player etc. The wife's laptop also has crashed with the new update as well .

Any suggestions? or is it a known/typical bug?
