From their website:

Greasemonkey is a Firefox extension which lets you to add bits of DHTML ("user scripts") to any webpage to change it's behavior. In much the same way that user CSS lets you take control of a webpage's style, user scripts let you easily control any aspect of a webpage's design or interaction.

For example you could:

* Make sure that all URLs displayed in the browser are clickable links
* Improve the usability of a site you frequent
* Route around common and annoying website bugs
