Greasemonkey slides into Chrome

In a blog post on Monday, Aaron Boodman, the developer of the Greasemonkey add-on for Firefox, announced that Chrome version 4 and later will support most of the JavaScript-coded Greasemonkey scripts without any additional tweaking.

This native support includes all available Chrome 4.0 builds for Windows, Mac and Linux, covering stable, beta and development versions. Chrome converts JavaScript directly into a Chrome extension as it is being installed, and the new add-on lives as an extension in Chrome's extension management window.

While this potentially adds 40,000 Greasemonkey scripts to Chrome's growing extension catalog, Boodman estimated that between 15 and 25 percent of them will not work on Chrome because of coding differences between Google's browser and Firefox.
