As of July 11, the main toolbar has been replaced in Firefix Android Nightly. It now takes up twice as much space, and that was just to add the forward and back buttons to it. Please add an option to return to the single row compact UI with the tab and menu button inline with the nav bar. The forward button is so rarely needed, and the back button is pointless because that's baked into android navigation buttons/gestures. The new toolbar is just so big with so much wasted space now.
