Whether you’re catching up on Facebook or speaking up on Twitter, the Greasemonkey browser add-on can make everything easier–if you’re using Firefox. Since the scripts are all user-written JavaScript-based tweaks, however, a few clicks will have you monkeying away with another browser of your choice. To get started with Greasemonkey, download and install the plug-in, and then check out “17 Greasemonkey Scripts to Turbocharge Your Browser.”
Internet Explorer
If you’re still using IE 7, you might want to try out IE7Pro, which offers similar support for user-created scripts. Though some Greasemonkey scripts will work on IE7Pro, compatibility isn’t guaranteed. Certain aspects of IE7Pro will work in IE 8, but it’s not completely implemented yet.
Google Chrome
Apple Safari
Apple hasn’t included any official support for user-created scripts for Safari on Windows or the Mac, but Mac Safari can use a combination of SIMBL and GreaseKit to get standard Greasemonkey scripts to work. Mac Safari users can also take advantage of the plug-ins and AppleScripts at Pimp My Safari.
Unfortunately, no equivalent SIMBL/GreaseKit combination exists for Windows Safari users, so you’re probably better off switching to Firefox (if you want Greasemonkey-specific support) or Chrome (if you want to use another WebKit browser with promising extensions).
