Hi there,

The menu bar is normally not shown by default, but it is activated when you hit the Alt key on your keyboard. If the game uses the Alt key, it should normally capture that keystroke and not send it through to the Firefox UI, but it sounds like that's not happening here.

One thing you can try is to enable the menu permanently and see if that changes the behavior. You can do this by right-clicking somewhere in the empty tab strip and then in the pop-up menu that appears, select the Menu.

Hope this helps!

Do you mean the location bar on the Navigation Toolbar?

Make sure that you do not run Firefox in full screen mode (press F11 or Fn + F11 to toggle; Mac: command+Shift+F).

If you are in full screen mode then hover the mouse to the top to make the Navigation Toolbar and Tab bar appear.
Click the Maximize button (top right corner of the Navigation Toolbar) to leave full screen mode or right click empty space on a toolbar and choose "Exit Full Screen Mode" or press the F11 key.

Does it help if you open a new window and open the pages in that window?
