"The single best extension for Firefox"
This extension can do so many things. With this extension you install things called scripts, they allow Greasemonkey to overwrite website Java code. Basically this program can do things like Remove ads, auto login to websites, secure your internet privacy, and MUCH MUCH MORE.
Greasemonkey can't automatically check for user script updates...
