We've long been fans of using user scripts to change the way the web works, but since Greasemonkey only runs on Firefox, Opera users are usually left out in the cold.


The Kabatology blog explains that even Opera users can use scripts designed only for Greasemonkey, by adding the Emulate GM Functions user script that provides the missing functions used by most of the popular user scripts. The process is fairly simple, starting with heading into the Advanced -> Content -> Javascript Options section of the preferences and assigning a folder to hold your user scripts. Once you've created the folder, add the Emulate GM Functions user script to it, and then start downloading some of your favorite scripts and saving them into your new user scripts folder.


You might not be able to use every single Greasemonkey script under Opera, but it's a great addition to the impressive-but-less-popular browser, and should work on any platform that Opera runs under. If you aren't sure what user scripts to use, make sure to check out our top 10 Greasemonkey scripts for 2009.
