Safari, Firefox "Quit unexpectedly" errors..HELP!!

I installed Leopard recently and am suddenly getting this quit unexpectedly error alot with either browser(Firefox or Safari) and I have already reinstalled both. I even tried other browsers such as Camino and Opera with same results. It happens on Ebay, youtube, Foxnews, and various other sites. Any help is greatly appreciated because it's getting VERY annoying!

search 'safari myspace battle' i have a post saying what to do. the same issue has risen with pretty every mac user using safari whilst on myspace. quits every 30 seconds.

I can't seem to find the thread..have a link anyone???
