NIS 2008 Pop-Up Blocker?

Apologies if this is a stupid question, but I really some advice.

I'm taking some online tests (that  need to be completed before Friday 5th Dec) and I need to disable all the pop-up blockers on my PC.  I've checked through the Norton Help pages, but I can't find an answer.

 

Does NIS 2008 have a pop-up blocker feature?

If yes, how do I disable it?

 

My system: Windows XP SP2

Browser: Firefox 3.0.3 (I've already enabled the pop-ups feature)

 

Many thanks,
