It is well documented how to add three elements to Adblock Plus for Firefox. However, I added another blocking rule to remove most of the remainder advertisements. The three Element Hiding Rules are facebook.com#*(social_ad) facebook.com#*(social_ad_advert) facebook.com#*(sponsers) I also added: http://www.facebook.com/ajax/emu/f.php?eid= Which resulted in many more ads being removed.
