another vote for adblockplus ^ and fwiw, check the settings/preferences once you install it to make sure that ads from "doubleclick"* are blocked. i can't remember if it's part of the default settings or not but i see no ads using firefox and ....... plus


*i also use safari with "safari ......." installed but about a month ago, i had to add "doubleclick" the the list of blocked ads as ads started showing up but as soon as i added doubleclick to the list, no more ads
