Rated 5 out of 5 stars

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.

Đánh giá này là cho một phiên bản trước của tiện ích (2.3.0a3). 

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