Flashblock blocking flash objects on CNET
Origins and Lineage

Flashblock is a content-filtering extension for the Mozilla Firefox- and Mozilla Application Suite-based web browsers. Flashblock allows users to prevent page elements, such as HTML object tag Browser plug-ins and advertisements, from being displayed.

The extension uses XBL and CSS to prevent elements of Silverlight, Java applets, Macromedia Authorware, Adobe Director and Adobe Flash from being displayed.[1] Contrary to common belief, Flashblock does not prevent the elements from being downloaded.[2]

Flashblock provides a mechanism that allows users to display the blocked elements by clicking on them, or by whitelisting.

Flashblock is based on a bookmarklet by Jesse Ruderman.[1][3]

Flashblock version 1.5.6 is compatible with Firefox 1.5 to 3.6a, Netscape 9 and Flock. Version 1.3.9 is compatible with most other Mozilla based browsers including older versions of Firefox.

Browser extensions by the same name have been created for Internet Explorer and Opera.
