'''Ad filtering''' or '''ad blocking''' is removing or altering [[advertisement|advertising]] content in a [[webpage]]. Advertising can exist in a variety of forms including [[Image|pictures]], animations, embedded audio and video, text, or [[Pop-up ad|pop-up windows]]. Very often it employs [[autoplay]] of audio and video. It is a known problem with most web browsers, including [[Mozilla Firefox|Firefox]], that restoring sessions often plays multiple embedded ads at once.<ref>[http://support.mozilla.org/en-US/questions/860098#question-reply http://support.mozilla.org/en-US/questions/860098#question-reply]</ref> All browsers offer some solution to the problem, either by targeting technologies (Flash/Shockwave, Window Media files, etc.) that are used to deliver ads, targeting URLs that are the source of ads, or targeting behaviour characteristic of ads (such as the use of [[HTML5 autoplay]] of both audio and video).
