Firefox addons

The coolest add on i found was called Destroy the Web.  Its a download that lets you choose any page and "destroy" it, but after the game is done the page goes back to normal.  After you download the add on a little button gets put on your toolbar.

This is a really fun game, and you can use this and challenge your friends and see who destroys the web better.

This is Google.com after I "destroyed" it.

This is the window that pops up telling you your score.

If you use Firefox as a browser then you should totally download this add on.
