If it’s Flash that’s causing your problems, you should try installing Flashblocker for Firefox: addons.mozilla.org
This could also be related to a Flash vulnerability that was just revealed today: littlegreenfootballs.com
But Flashblocker should solve this too, because it simply stops Flash content from loading unless you want it to.
But it costs you the revenue because the flash ad is never loaded.
