As soon as you restart Firefox the Menu Bar is already hidden as shown below (nice!).
So what do you do when you need that occasional access to the Menu Bar?
Just hit the left or right Alt Key…it acts just like a toggle switch.
The Menu Bar will also auto-hide whenever you click inside the webpage or outside of the online window itself.
