I was using the Firefox browser on my laptop on the floor. My little sister stepped on the far left part of my keyboard and did some sort of shortcut so now it won't show my tabs open or the search bar unless I put my cursor to the top of the screen. Also, my taskbar does not show at the bottom of my screen anymore unless I hit the window button on my keyboard. Can someone please help me put it back the way it was? Is this the right way to contact someone about this problem?

Thank you, Rachel

Sounds that she switch the laptop to Full Screen mode (press F11 to toggle).

When you are in Full Screen mode, hover the mouse to the top of the screen to make the Navigation Toolbar and Tab bar appear. Right-click empty space on a toolbar to find "Exit Full Screen mode" and "Hide toolbars".

You can use one of these to leave Full Screen mode:

  • press the F11 key
  • click the Maximize button at the right end of the Tab bar
  • click the Full Screen button in the "3-bar" Firefox menu button drop-down list
