block popups

How do I block popups from a website where I previously allowed them? Ebay tried to open a popup and I allowed it, thinking it was something I might want to see like a message, but it turned out to be advertising; now I can't find any way of blocking them. When I go to Exeptions, all I get the option to do is ALLOW popups from a site, not block them!

In the Allowed Sites - PopUps window, click to highlight the website that you want to remove that "permission" for and then click Remove.

Hi, thanks for the help, unfortunately in the Allowed Sites - Popups window, I just have a long list of blocked sites, and nothing else? There are no 'allowed' sites in the list (despite the fact that I do have some 'allowed' sites)
