Greasemonkey is a userscript manager made available as a Mozilla Firefox extension. It enables users to install scripts that make on-the-fly changes to web page content after or before the page is loaded in the browser (also known as augmented browsing).

The changes made to the web pages are executed every time the page is viewed, making them effectively permanent for the user running the script.
