Hi, I use Firefox 0.9 (FF) as my main broswer. I recently registered and I noticed there was a pop-up that FF was blocking, so I told the program to allow it. Sure enough, the popup comes and goes but I can't see any apparent reason for it.

So I'd like to ask the powers that be at UT what does this pop-up do? Can I tell FF to block it as it did before?
