AdBlock is a content-filtering extension for the Google Chrome and Apple Safari web browsers. AdBlock allows users to prevent page elements, such as advertisements, from being displayed. AdBlock is the most popular extension for Google Chrome.[1] According to an article in The New York Times,[2] the extension was created on December 8, 2009 (the day that support for extensions was added to Google Chrome). Safari support was added in June 2010.
AdBlock is not to be confused with Adblock Plus For Google Chrome(tm), the Chrome version of the popular Firefox plugin, which is a blend of the source code of former Chrome plugin AdThwart and Adblock Plus' Firefox version.

As of Version 2.5, the add-on blocks the download of all advertising resources, including ads in videos and in Flash.
Version 2.1 added internationalization. As of August 2011, AdBlock supports over 25 languages.
Version 2.4 saw many speed improvements - reportedly, the extension is twice as fast, while loading less memory per tab.[3]
AdBlock uses the same filter syntax as Adblock Plus for Firefox and natively supports Adblock Plus filter subscriptions. Filter subscriptions can be added from a list of recommendations in the "Filter Lists" tab of the AdBlock options page, or by clicking on an Adblock Plus auto-subscribe link.
Users can also add their own filters in the "Customize" tab of the options page; they can be added automatically from the right click or toolbar menus.
