Firefox Query

FIREFOX QUERY….Technical questions for the masses. I’m using Firefox, and on certain web pages my system slows down to a crawl. When I bring up Task Manager it reports that Firefox is sucking up 95% of my CPU time. As near as I can tell, it seems to be related to advertisements that use Flash: some of them cause the system to go crazy by sucking up every CPU cycle they can get their hands on. Or maybe it’s certain Java or Javascript applications. I can’t tell for sure, but in any case it seems to be clearly related to some kind of bug in certain advertisements.

Anyone else ever come across this? Any solutions?
