Firefox spyware cookies

Ok I posted this before but I forgot to check it and it disappeared off the board. When I use IE, spybot passivly blocks spyware cookies. When I use firefox it just collects them since spybot dosn't work on it. So the question is what program can I use with firefox to block the cookies?
