One of the problems with using the Greasemonkey extension for firefox is knowing what scripts are available for the site you are visiting. Greasefire is a companion extension designed to help you customize your web browsing by finding user scripts for any page you’re currently visiting.
Once installed, the extension automatically searches the Greasemonkey script repository Userscripts.org for scripts related to the site you’re visiting. If a script is available, the Greasemonkey icon in your Firefox status bar will display a fiery background to indicate that it found matches.
