Greasemonkey Scripts

Greasemonkey is a popular and powerful add-on to the Firefox browser that allows JavaScript script files to be run on any web page. This allows users to alter the client side page to aid with usability and to improve on the features that the page already contains.

The scripts are user created, normally with the intention of providing more information or reformatting of the already present information on a specific web page.

These types of scripts can be very powerful, but remain limited to the information that is provided by the server to the web browser.
