GreaseKit – Use GreaseMonkey’s User Scripts in Safari
GreaseMonkey is a very powerful Firefox add-on that lets us make on-the-fly changes to websites we visit by installing user scripts. Simply put: that means we have more control over websites we visit. For example, we can add a ‘download’ link to Youtube video pages and remove annoying quizzes from our Facebook homepage.
Neat innit? The problem is: GreaseMonkey cannot be installed in Safari, Mac OSX’s default browser (and by far my favorite one). Solution: GreaseKit. Here’s how.
First we’re going to have to install SIMBL. SIMBL is a software that lets you modify Cocoa applications. In this case, we’re modifying Safari.
After installing SIMBL, we can now proceed to installing GreaseKit (download it here). GreaseKit is not an application, it’s a SIMBL add on. Double click the DMG file and you’ll see this file:
Drag GreaseKit.bundle to OSX (this being your system root) > Library > Application Support > SIMBL > Plugins.
Now restart your Safari app and check the menu bar, there will be an additional menu that says GreaseKit. That does it, now you can browse the available user scripts and install the ones you like :)

@WindowsUser I think you’re stuck with Firefox + GreaseMonkey for now :)
