Greasemonkey is a Firefox add-on which uses small chunks of JavaScript to customise how a web page works.

Greasemonkey extends Firefox by providing easy access to a huge range of scripts. Beginners can use it without worrying about the fine details, but if you're a JavaScript expert then it also gives you plenty of site-customising power. Greasemonkey makes the process a lot easier by enabling you to both find and create scripts online. Greasemonkey is similar to Yontoo Layers in that it is a Firefox plugin that allows you to apply JavaScript to web pages which changes their appearance and behavior. Wikipedia: 'Greasemonkey is a Mozilla Firefox extension that allows users to install scripts that make on-the-fly changes to HTML web page content on the DOMContentLoaded event, which happens immediately after it is loaded in the browser (also known as augmented browsing).'

You don't have to know anything about JavaScript to use Greasemonkey, as there are plenty of free scripts available. And it's surprising just what they can do. As we write, one repository (Greasy Fork) has scripts to avoid ads, extend YouTube, bulk-delete items from your Facebook timeline, download videos, translate text, check Rapidshare links, download Instagram and Facebook albums, and automate, fix and enhance just about every aspect of Kings of Camelot (and that's just on the first three pages).

These scripts can be almost as powerful as add-ons, and they're usually just as easy to install. Find something you like at Greasy Fork, click the link to read more, and if you like the sound of it, click 'Install this script'. A warning dialog explains what you're about to do, so there's no risk of silent installations. There's an option to view the script source, but otherwise you can install it with a click. Installed scripts can then be accessed via an extra tab on the Addons page, where you'll find buttons to set options, disable or remove them.

Greasemonkey also provides simple tools to create and manage your own scripts (click the Greasemonkey button on the address bar and choose 'New User Script'). Even experts may find it a challenge to get everything working, but fortunately Greasemonkey has a comprehensive wiki to offer help and advice.
