A must-have Rated 5 out of 5 stars

This is the first extension I install on any Firefox I use!
Absolutely a must-have.
And for those ranting that it's hard to use or that it is flawed, please do some research for more than 5 minutes, the web is never the same once you know your way around Greasemonkey!

This review is for a previous version of the add-on (1.4.1-signed).
