Fix for 'hide Henu Bar' persistence bug. Rated 5 out of 5 stars

Win7x64 & FF3.6
The option to hide the Menu Bar and then to show it temporarily by pressing the alt button, would not persist after restarts. ie. I had to re-enable Menu Bar, restart FF and then re-hide Menu Bar, to recover functionality.
Until this fix. Thank you!
