If you spend a lot of time working with your browser, it’s very likely that you’ve heard of Userscripts. As the name suggests, user scripts are small code snippets meant to enhance your browsing experience. Scripts simply edit some aspects of your favourite web pages thanks to some css and / or javascript.
There are scripts that works with google.com, Facebook, Twitter…every famous website out there, mostly. These scripts are usually loaded with a browser extension: on Firefox we have Greasemonkey and on Safari its less known brother, GreaseKit.
