Make sure your Firefox doesn't have any extension that can cause there pop-ups to occour. And what kind of pop-up blocker do you use? if its anything other than AdBlock Plus, then remove it and get that one.
Here is a lethal combo for all firefox users: (filterset.G is outdated and no longer supported)
Adblock Plus

Adblock Pluss: Element Hiding Helper
https://addons.mozilla.org/en-US/firefox/addon/4364
Adblock Plus Filter Uploader
https://addons.mozilla.org/en-US/firefox/addon/4042
With there 3, ads are history.
Thanks. I implemented all these, and now there's only one way to see if they really worked, the ol' wait-and-see method.
