FireFox buggy with high clock speeds

I have run prime and superpi with no stability issues, but FireFox is buggy when I go past 4GHz. I just turned up the wick today, and at 4.4GHz the gifs in FF are haulin butt. They are moving so fast it is distracting. Sigs and avatars are like strobes. IE does not have this issue, so I may have to go back to using it Is there a patch for FF that addresses this issue?

Thanks

EDIT: maybe this would have been better off in software? Oh well, if it gets moved so be it.

PS, my scroll wheel also acts jerky with FF. IE does not have this issue either...

Have you updated to the latest firefox? I have noticed that FF can be a decent gauge of computer stability, even if it wasn't intended to be.
