Customizing toolbars while in fullscreen mode can make toolbars inaccessible off top of screen
The following steps will lead to the toolbars disappearing off the top of the screen, and full screen mode un-exitable except via the keyboard shortcut F11. 1) Make sure you have the menu bar disabled, so you have the menu button on the tab bar instead. 2) Enter fullscreen mode. 3) Via the menu button, choose Preferences > Toolbar Layout... to customize toolbars. 4) Wait for the toolbars to auto-hide. 5) Hit "Done" in the "Customize Toolbar" dialog to end customize mode. After this, the toolbars no longer re-appear when the mouse touches the top of the screen. The vertical scrollbar also appears to have its top cut off, which suggests that the top of the window moved above the top of the screen. I'd guess that the window size adjustments that occur when leaving the "Customize Toolbar" mode interacted badly with fullscreen mode.
I can still reproduce this bug in Firefox 57, following the same procedure documented above (other than using "Customize" in step 3 to customize the toolbars): 1) Enter fullscreen mode. 2) Via the menu button, choose Customize... to customize toolbars. 3) Wait for the toolbars to auto-hide. 4) Hit "Done" on the customize page to end customize mode. After this, the toolbars no longer re-appear when the mouse touches the top of the screen.
One additional observation: when this does happen, sometimes moving the mouse away from the top of the screen and back to it will work. But the initial press of the mouse against the top of the screen doesn't produce the toolbar at all.
