How to Exit Full Screen in Mozilla Firefox

Many apps, including popular Web browsers like Mozilla Firefox, have an option that lets you enter full screen mode. This allows the browser to take up the full size of your monitor, thereby making your Web pages larger and easier to read, while also minimizing distractions from other applications. But you may be wondering how to exit full screen in Firefox if you are done, or didn’t mean to enable it in the first place.

More Information on How to Exit Full Screen Mode in Firefox

  • You can exit full screen mode in many other apps by using this same method. For example, Google Chrome is controlled in the same manner.
  • In newer versions of Firefox you can move your mouse to the top of the screen over the Firefox window, which will give you access to the menu by clicking the button with three lines. Next to the “Zoom” option is a button with two arrows pointing in opposite directions. You can click that button as well to exit full screen mode.
  • If you are using multiple monitors then putting Firefox into full screen will only take up one of those monitors. This means that you can have Firefox expand to fill that screen, while still working on the other one. But when you press the F11 key it is going to control whichever app is the one that is currently active. So it’s possible to put another app into full screen accidentally if your mouse is on one of your other screens.
