Should be implemented in FF UX by default! Rated 5 out of 5 stars

This addon is in a league of its own; it's one of the few extensions that are so useful and convenient, they should eventually be implemented in the Firefox UX design by default! Like a few other "must-have" addons, it's tough to imagine using FF without this ability. The developer of this addon deserves every ounce of praise he or she is receiving for it.
