GreaseMonkey

GreaseMonkey is a Firefox addon i've been using for a while, i think it will be useful to everyone. GreaseMonkey lets you add a Javascript to a site or sites - changing/adding adjustments to the site that only you can see. For example you can add a script that lets you download DivX files from video sites like stage6.

To download GreaseMonkey(Firefox only):

To download the DivX download script:
http://userscripts.org/scripts/show/12589

To install a script:
1. Install GreaseMonkey and restart Firefox.
2. Find a script you want to add and view it(in your browser, no need to download).
3. Go to Tools > Greasemonkey > New Script. Now a dialog will show, wait a few seconds and click on Install, if the script is installed you will see a message in the status bar that confirms the installation.
*4. Notice the monkey head icon on the bottom of your browser, if you click it you can enable and disable GreaseMonkey.
