I can allow pop-ups from certain sites in Tools/Settings, why then can I not also block pop-ups from certain sites since Firefox doesn't always manage to block them?

Whenever I visit, for instance, merriam-webster.com an ad from groupon invariably pops up in a new window. OK, so Firefox does not manage to block it although I have this option checked in Tools/Settings/Content. But why can I not enter the URL of the groupon ad and manually block it? I can allow pop-ups from sites of my choice in Tools/Settings/Content, I think I should also be able to block sites?
