Chromium gained an important patch over the weekend, with the introduction of Greasemonkey support. The patch came from none other than Aaron Boodman, creator of the original Firefox add-on, and also a Google employee.
For now, it’s just a patch and it’s not yet clear if and when it will be part of the official Chrome release. As GHacks explains:
Since there is no way of adding extensions to Chrome yet users have to live with some limitations. Only scripts in c:\scripts are loaded and only if the user adds the parameter –enable-greasemonkey by appending it to the program’s shortcut.
