How to Exit Full Screen in Mozilla Firefox: A Step-by-Step Guide

Exiting full screen in Mozilla Firefox is pretty straightforward. Simply press the “F11” key on your keyboard, and voilà, you’re back to the normal viewing mode. It’s a quick and easy process that gets you out of full screen and lets you access other parts of your desktop or other windows you have open.

After completing the action, your Mozilla Firefox browser will return to its standard window size, allowing you to view your taskbar, other browser tabs, or applications that you may have open simultaneously.


Full screen mode in Mozilla Firefox can be a nifty feature when you want to eliminate distractions and focus solely on the content in front of you. Whether you’re watching a video, reading an article, or presenting a web page, full screen mode maximizes the webpage to fill your entire screen, hiding all other elements, including the browser’s toolbars and the taskbar. But what happens when you need to get out of it? Maybe you need to check a notification, or you simply want to multitask. Knowing how to exit full screen in Firefox is crucial for a seamless and efficient browsing experience.

This article is particularly important for those new to Mozilla Firefox or for users who may not be tech-savvy. It’s also relevant for users who have accidentally entered full screen mode and are unsure how to revert to the normal display. So, if you’ve found yourself stuck in full screen and are frantically pressing keys to escape, take a deep breath, and let’s walk through the steps together.

Step by Step Tutorial: How to Exit Full Screen in Mozilla Firefox

Before we dive into the steps, it’s worth mentioning that exiting full screen mode will allow you to access your browser’s menu, extensions, and other applications on your device. It’s a simple process that won’t affect any of your open tabs or ongoing work.

Step 1: Press the “F11” Key

Press the “F11” key on your keyboard.

This is the quickest and most common method to exit full screen in Firefox. The “F11” key is typically located on the top row of your keyboard. When you press it, the browser should immediately switch out of full screen mode.

Step 2: Use the Exit Full Screen Button

Move your cursor to the top of the screen to reveal the toolbar, then click the exit full screen button.

In case the “F11” method doesn’t work, or you’re using a device without a keyboard, this method can be your go-to. The exit full screen button usually appears as a small icon with two diagonal arrows pointing inward.


Ease of UseExiting full screen mode in Firefox is incredibly user-friendly. Anyone, regardless of their technical knowledge, can perform this task with ease.
Quick Access to Other ApplicationsBy exiting full screen, you can quickly switch to other tools or applications without minimizing or closing your browser first.
Uninterrupted BrowsingExiting full screen doesn’t disrupt any ongoing activities in the browser. All tabs and activities remain as they were.


Accidental ExitSometimes, it’s easy to press the “F11” key accidentally, which can be disruptive if you were intentionally using full screen mode.
Hidden ToolbarIf you’re not familiar with the feature, it may not be immediately obvious how to access the toolbar and buttons to exit full screen.
Device CompatibilityThe “F11” key method may not work on all devices, especially tablets or devices without a physical keyboard.

Additional Information

While the steps above are pretty simple, there might be times when they don’t work as expected. For instance, if your keyboard is malfunctioning or if you’re using a device where the “F11” key serves a different function. In such cases, you can try using the menu button at the top-right corner of Firefox (it looks like three horizontal lines) to exit full screen. Here, you’ll find the “Exit Full Screen” option under the “View” menu.

Another point worth noting is that certain web applications can request to go full screen and may provide their own mechanism to exit full screen. In such scenarios, look for an exit button within the web page or application itself.

And remember, if you’re ever stuck, Mozilla Firefox’s support pages offer extensive help and guidance on managing browser settings, including full screen mode.
