Why would you watch TV in Black and White when you can experience it in colour and high definition? Then why are you experiencing the web as is?

Userscripts.org has thousands of scripts, lightweight Web Browser applications, created by a community of thousands of developers, that enrich your experience of web sites you already use. Firefox users need to install the Greasemonkey plugin to use userscripts.

Here are some of the best userscripts I’ve used.

YouTube Enhancer

This script adds a ton of awesome features to enhance your YouTube. Here is a summary:

Under the player you can select the quality you want to view. Resizing of the video to collapse, wide or 4:3. A Media Controller, i.e. Stop button, Step forward or backward, Loop and a Kill button which stops the video and the streaming completely. Download links for the video. Keyboard shortcuts

Facebook Fixer

I previously mentioned a neat Facebook userscript called Facebook Purity that removes all the crap that people share on their wall. Now this plugin adds a load more features:

Big Profile Pictures and Photos, Big Album Pictures, Video Download Links, Load Full Albums, Homepage Customization recently improved, Bookmarks recently added, Localization recently improved, Translation, Age and Sign, Calendar Integration, Keyboard Shortcuts, Re-Title recently improved, Error Page Reloading. This plugin also has the option to hide certain wall posts like the Purity script did.
