Excellent!



I have a small comment, though. I updated to the new version, and since then, every time I start or restart Firefox, an empty menubar keeps showing up and I have to close it manually.
It wasnt happening before the update.

This review is for a previous version of the add-on (2.3.0a3). 

Which version of Firefox or Thunderbird using?
Please tell me prefs data "compact.menu.hidetoolbar.*" (enter "about:config" in location-bar.)
