How do I get off the mozilla support page?
I don't have any "x" or "+" at the right top corner of this page. How do I minimize or "x" out of this page?

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 of the screen 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.
You should be able to close a tab via the Ctrl+W shortcut. If this is the only tab then first open a new tab (Ctrl+T) to prevent closing Firefox.
