How to Activate Full-Screen Mode in Firefox

This tutorial walks you through it step-by-step on the Windows, Mac, and Linux platforms.

Open the Firefox browser. To activate Full-Screen mode, select the Firefox menu, located in the upper-right corner of the browser window and represented by three horizontal lines. When the pop-out menu appears, select the full-screen icon. It’s a short line with two arrows pointing to opposite corners. You can see it highlighted in the image below. You can also use keyboard shortcuts in place of this menu item. On a Windows PC, press F11. On a Linux computer, press F11. On a Mac, press Command+Shift+F. To exit Full-Screen mode at any time, select the full-screen icon or use one of the keyboard shortcuts a second time.
