The Only preventing 5 Stars is Rated 4 out of 5 stars
This App has not been updated since the Beginning of 2009! We have the newer Firefox 4 and is vastly different from other Versions of Firefox. Reason, most likely, Greasefire has not been compatible. If it is a monetary thing? Well, I have no problem donating to developers who provide an excellent service with their dedication on making Firefox truly a personalized experience for the end user.This review is for a previous version of the add-on (1.0.4).
