essential FF3 beta tool Rated 5 out of 5 stars
If you're testing the latest Minefield build or are just an early Firefox 3.0 adopter, this extension is a must-have. Though, please don't use it for evil and try and run completely incompatible extensions that haven't been updated in years... you will regret it. ;)This review is for a previous version of the add-on (1.3).
