''Never be annoyed by a Flash animation again! Blocks Adobe Flash  so it won't get in your way, but if you want to see it, just click on...''

Flashblock is an extension for the Mozilla, Firefox , and Netscape browsers that takes a pessimistic approach to dealing with  Adobe Flash  content on a web page and blocks ALL Flash content from loading. It then leaves placeholders on the web page that allow you to click to download and then view the Flash content. Flashblock currently blocks the following content types:
 * Adobe Flash
 * Adobe Shockwave
 * Macromedia Authorware
