hello gstoner, please refer to [[Navigation buttons like back, home, bookmarks and reload are missing]] - hopefully it will contain a solution to your issue...

Note that you can always bring up a replacement location bar via the Ctrl+L shortcut. Also make sure that you do not run Firefox in full screen mode (press F11 or Fn + F11 to toggle; Mac: Command+Shift+F). *https://support.mozilla.org/kb/how-to-use-full-screen 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. ----- See also: *http://kb.mozillazine.org/Prevent_websites_from_disabling_new_window_features
