Google Chrome 4 now natively supports Greasemonkey user scripts

One thing that got lost in the commotion of the extensions launch is a feature that is near and dear to my heart: Google Chrome 4 now natively supports Greasemonkey user scripts. Greasemonkey is a Firefox extension I wrote in 2004 that allows developers to customize web pages using simple JavaScript and it was the inspiration for some important parts of our extension system.

Installation is quick and easy, just like installing an extension. That’s because under the covers, the user script is actually converted into an extension. This means that management tasks like disabling and uninstalling work just like they do with extensions.

Also keep in mind that some user scripts won’t work in Google Chrome yet, because of differences between it and Firefox. Based on some analysis that the current maintainers of Greasemonkey did, I expect between 15%-25% of scripts to not work in Google Chrome. If you find such a script, you should consider letting the author know. There may be something he or she can do to easily fix the problem. In the meantime, we’ll keep working on bugs on our side to bring our implementation closer to Greasemonkey.
