Rated 5 out of 5 stars

Greasemonkey is an innovative, practical and particularly usefull add-on for technically adapt users. Ever since I first downloaded it, I don't believe there has been a day without it. However if you wouldn't count yourself as one of the technically savvy, you may find it hard to grasp and use. I would recommend that if you have trouble grasping technology, do not download.

This review is for a previous version of the add-on (0.7.20080121.0).
