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.
You can click the Maximize button at the top right to leave full screen mode or right click empty space on a toolbar and use "Exit Full Screen Mode" or press F11.

Even after I toggle F5 or F11 and get the smaller window, there is still no address bar/place to enter a web address. This is why I still use Windows Internet Explorer; at least you don't have to "toggle" things to use the web.

Many of my colleagues deride Explorer, but I just don't get it. I don't want to spend my time using 2-3 extra keystrokes when with Explorer it's just point and click. Explorer may be a little slower, but it's faster than hitting a bunch of extra keys just to navigate the web.

If the menu bar is hidden then press the F10 key or hold down the Alt key, that should make the menu bar appear.

Make sure that toolbars like the "Navigation Toolbar" and the "Bookmarks Toolbar" are visible: "View > Toolbars"

• If items are missing then open the Customize window via "View > Toolbars > Customize" or via "Firefox > Options > Toolbar Layout" (Linux, Windows)
• If a missing item is in the toolbar palette then drag it back from the Customize window on the toolbar
• If you do not see an item on a toolbar and in the toolbar palette then click the "Restore Default Set" button to restore the default toolbar set up.
