Excellent. Rated 5 out of 5 stars
A very well replacement for the statusbar. I'm currently using a FF4.0b7nightly from around 2.nov and losing the statusbar sucked. Though replacing it with a addonbar is a nice idea. Your addon gives us the statusbar back. It might be even better.
BTW: Since every FFuser right in his mind should use noScript and a Cookiemanager, which are using buttons in the statusbar (now addonbar), the thought of removing the bar to give more reading place was a nice idea, but total nonsense. Till they find a better way to place this icons, the bar is there to stay.
And yaaaa... I worship you. ^^
