Very happy! It works! Now tell me why with Firefox 57, Quantum, when I select from the menu bar, the menu instantly disappears when I hover over it with the mouse. Uninstalled Gesturefy and the problem went away.
If by menu bar you mean this: https://www.maketecheasier.com/assets/uploads/2015/07/restore-firefox-menu-bar-example1.png then it's totally unrelated to Gesturfy.
