Greasemonkey by Anthony Lieuallen

Allows you to customize the way a web page displays or behaves, by using small bits of JavaScript.

You can write your own scripts, too. Check out http://wiki.greasespot.net/ to get started. Many scripts already exist, probably ones to enhance your favorite sites. Find them at http://wiki.greasespot.net/User_Script_Hosting .
