CNET News.com has an article about an extension for Mozilla Firefox called Greasemonkey. First released late last year, the Greasemonkey extension lets users install small pieces of JavaScript that change the behaviour or display of Web pages. These pieces of code, called user scripts, can be set to affect every page you visit or just those for a particular site. The extension comes preinstalled with a script that changes all underlined text on Web pages to italics (to avoid confusion with links) and one of the many site-specific Greasemonkey user scripts automatically changes the colours used on Slashdot. More advanced scripts are available too, including one that adds a persistent search feature to Gmail.
