Rated 4 out of 5 stars

This was an excellent add-on in it's day, but I thought I would point out something I just now discovered for myself: for all of you who come here wishing this didn't mess with your bookmark functionality, I'm betting the add-on maker isn't updating it because this functionality has been incorporated into Firefox itself. If you disable this add-on and restart, then right-click on any of the toolbars and uncheck "menu bar" then you get an orange Firefox button beside the tab bar, exactly as this extension gives you. There's no need for other versions of this extension, unless you like the cosmetic look of those alternatives, or you want to customize what appears in the menu that pops out when you click the Firefox button.
