You have to tell it what ads to block. The easiest way is to just install another extension along with Adblock called Filterset.G (ya, weird name). It will keep Adblock's list of evil ads updated automagically for you.Caitlyn said:How do I actually get it on? Like, when I installed it, I just left it alone and ads were still there. I know NOTHING about Firefox extensions. Thanks for the reply.
