IE9 anyone?

You could also contact Firefox and see if they can find out how that particular website is getting through the popup blocker.

I have a suspicion there may be some sort of spyware or other infiltration that's occured.  I have a couple of friends who use AdBlocker and Firefox and have no issues, whatsoever, so they may be able to offer up some clues, too.  Thanks for you insight.
