Greasemonkey is a Firefox extension that allows users to install scripts that make on-the-fly changes to most HTML-based web pages.
As the Greasemonkey scripts are persistent, the changes made to the web pages are executed every time the page is opened, making them effectively permanent for the user running the script.
Greasemonkey can be used for adding new functionality to web pages (for example, scripts for Facebook), fixing rendering bugs, combining data from multiple webpages, and numerous other purposes.
Most of the Facebook hacks and addons we provide include userscripts which only work if you have greasemonkey installed.
Though greasemonkey was intended for Firefox only, but compatible third party softwares have come up adding userscript functionality to most of the major browsers. We have written browser specific guides which will allow you to run and install userscripts on Firefox, Internet Explorer, Google Chrome and Opera Browser.
You must proceed further if you have firefox as your browser. For other browsers, please choose your browser specific tutorial from the tutorials we just listed above.


Please note that installing Greasemonkey is different from installing greasemonkey ‘Userscripts’. For the latter, you can get step by step instructions for installing userscripts in your respective browser:
