Greasemonkey comes to Chrome

Greasemonkey scripts are an easy way to create single-serving enhancements for Firefox, and now they work natively on Google Chrome, too.

In a blog post 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 necessary. This includes all available builds for Windows (stable | beta | dev), Mac (beta | dev), and Linux (beta | dev). Chrome converts the JavaScript directly into a Chrome extension as it's 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 estimates that between 15 and 25 percent of them won't work on Chrome because of coding differences between Google's browser and Firefox.

He rightly warns readers that Greasemonkey scripts can give the script author unfettered access to personal data, so it's important to check reader comments and ratings before casually installing one. In my test of Flickr Image Size, a script that forces all available images sizes to appear as links in Flickr, I encountered no problems.
