Rated 5 out of 5 stars

This is a great add-on. If you can find a way to navigate the unorganized scripts library at http://userscripts.org/, you can find some pretty amazing scripts that will enhance browser functionality. Greasemonkey does slow down FF startup time a bit, but because I added some scripts to modify the Google search results, it speeds up my searching considerably (and reduces the irritation factor).

This review is for a previous version of the add-on (0.9.18.1-signed).
