Rated 5 out of 5 stars

EVERYBODY WHOS INSTALL THIS ADDS-ON PLEASE NOTICE THE AUTHOR WILL NOT UPGRADE ANY MORE!
firefox 3.6, as author said, can hide your menu bar. Just right click around menu bar ,toggle off the menu bar.
To reveal menu bar, please install the author's latest adds-on "Auto menubar". IT will automatically show the menubar when your mouse moves to the title of the firefox window.

This review is for a previous version of the add-on (1.0.20091221).
