Rated 4 out of 5 stars

Combine this with a unified stop and reload buttons extension, let us customize the keys and this extension's a must!

This review is for a previous version of the add-on (1.0). 

Key customization is now available as of version 3.0.0, and unified stop/reload is now available as a core feature of Firefox 4 and above. Hope you'll consider upping your rating!
