Greasemonkey

Firefox extension allowing a JavaScript to be "mixed" into a browsers page. Provides a very effective means of making quick browser based hacks on sites outside of your own control.

Greasemonkey scripts can eventually be turned into full fledged Firefox extensions to allow others easier access to installing your script (without the need for other people to first install Greasemonkey).
