Has more potential... Rated 3 out of 5 stars
I found this useful as I'm simply very "anti-menu" when browsing. That said I think you're not exploiting it's full potential. FF simply falls short on the actual sidebar stakes which is where the ability to have one either side on screen with user installed widgets embedded is where I think you should take this further. The optional "self hiding" should stay though.This review is for a previous version of the add-on (0.2.9.1-signed).
