YouTube Full Screen Not Working on Google? How to Fix It

Watching videos on YouTube in full screen on Google is one of the best ways to enjoy content, providing an immersive experience. However, you may experience issues where you can't go full screen on YouTube web, getting frustrated and inquiring why my full screen button is gone on YouTube. If you've clicked the full screen button only to find it not responding, you're not alone.

This guide will provide the common causes of YouTube full screen not working on Google and solutions to fix this situation.

Part 1: Why is my YouTube Full Screen Not Working?

There can be several reasons why YouTube won't go full screen on Android or the web, ranging from browser glitches to hardware issues. Let's have a look:

1. Too much Cache Data

Over time, browsers accumulate cached files, cookies, and data that can interfere with websites. An overloaded cache may lead to display errors, such as buttons not responding, including the full screen feature on YouTube.

2. Outdated Browser

An outdated browser results in compatibility issues with modern websites like YouTube. New updates are crucial to ensure your browser functions properly, including supporting full screen playback for video platforms.

3. Page Loading Issue

A slow or incomplete page load can sometimes prevent YouTube full screen function from working properly. If the page doesn't fully load, certain features, including the full screen button, may not be functional.

4. Wrong or Not Enough Setting of Browser

If your browser settings block certain permissions, such as allowing full screen or using certain web APIs, YouTube may be unable to enter full screen mode. Ensuring these settings are properly configured can help resolve the issue.

5. Full Screen API Issues

Modern browsers rely on the Full Screen API, which allows websites to enable full screen mode for videos and other content. If your browser does not support or disable API, YouTube may not display in full screen.

Part 2: Five Ways to Fix YouTube Full Screen Not Working

After exploring the causes, let's implement five ways to solve the issue and get YouTube back to full screen mode:

1. Refresh the Page

Sometimes, refreshing the page can resolve temporary glitches. Press the refresh button or hit "F5" to reload the YouTube video, and then try the full screen button again.

2. Clear Browser Data

An overloaded cache can interfere with website performance. Clearing your browser data can resolve this issue. Here are the steps to clear the browser cache:

• Open your browser settings and navigate to "Privacy and Security."
• Click "Clear browsing data" and choose "Cached images and files."
• Press "Cookies and other site data"> "Clear browsing data."

After clearing the data, reload YouTube and check if the full screen issue persists.

3. Reinstall and Reopen the Browser

If refreshing the page and clearing the cache doesn't work, reinstalling the browser might help resolve the issue. Reinstalling ensures you're running the latest version of the browser, with default settings that often fix any configuration issues. Here is how to reinstall the browser:

• Uninstall your browser from your computer.
• Go to the official website of the browser to download the latest version.
• Install and reopen the browser.

Test YouTube in full screen mode after completing these steps.

4. Check the Content Setting of the Browser

Some browsers, especially those with stricter privacy settings, may block features like full screen video mode. Let's follow these steps to check the content setting of the browser:

• Open "Settings" in your browser.
• Now, navigate to "Privacy and Security."
• Look for "Site Settings." Check that YouTube is allowed to enter full screen.

5. Check Firefox Full Screen API

If you're using Firefox and can't full screen on YouTube web, it might be due to the Full Screen API setting. Here is a tutorial to enable full screen API in Firefox:

• Type "about:config" in the address bar. Then, hit Enter.
• Search for "full-screen-api.enabled."
• Make sure the value is set to "true."

Once this is done, restart Firefox and check if YouTube can go full screen.
