It's probably Flash. Flash + FF is not yet a terribly friendly pairing. There's one of those stupid intel quad core ads (the one with the leopards) that causes my machine to hit 100% CPU usage everytime. I couldn't, easily, test this on IE as browser detection on the server side was returning a single GIF to IE but a .swf to FF. No idea why. I gave up at the point and just install FlashBlock!

I for one have gone back to using Safari as my browser of choice. There have been content rich pages (like the World of Warcraft Armory pages) which have caused Firefox to choke and consume 100% of my CPU speed for 5 - 10 seconds before successfully loading the pages.
Just taking this article as an example. Safari uses about 10% CPU power to display the page and the adverts. Once the animations complete, CPU usage drops to 0 - 3%. In contrast, Firefox 20 - 30% CPU usage to display that page and when the animations are done, CPU usage drops to about 5 - 10%.
This is really sad, as I much prefer Firefox since more pages render correctly.
