Gone are the days when Facebook was just meant for posting your pictures. Millions of entertaining and informative videos are uploaded daily on the platform. And that's why many people love to watch Facebook videos on a browser for a better visual experience.

But lately, many users have reported that Facebook videos not playing correctly in FireFox. It is a severe mood killer and can happen to anybody, anytime. So if you're having this issue, then cheer up.

Below are some simple workarounds to troubleshoot Facebook video-related problems on every browser. Make sure you read the article until the end to get rid of this issue.

Part 1: How to Fix Facebook Videos Not Playing in Chrome/Firefox/Safari?

This section aims to provide common reasons for Facebook videos not playing along with how to fix it. Let’s take a quick look!

1. Restart Your Router

A slow internet connection is the leading cause of issues in playing Facebook videos. If your internet is weak or disconnected, Facebook videos won’t play no matter what you do. So, the first thing you should be doing is test the internet speed.

Just open another webpage and refresh it. If it loads quickly, then your internet is working fine. If not, using a third-party program like SPEEDTEST or Ookla gives you a hint about the performance of your internet. If it isn’t satisfactory, restart the Wi-Fi router. More often than not, it automatically addresses the internet issue. Else, you need to contact the internet service provider and request them to fix the internet connection.

2. Restart Your Browser

A minor browser bug can often be why Facebook videos are not playing in Chrome. It can happen for many reasons and interrupts the normal loading of applications, including Facebook videos. The quickest way to fix it is by restarting your web browser. Luckily, the process is as simple as it can get. Check out the below steps for refreshing the browser on different web browsers.

On Chrome

• Open the Chrome browser.

• Hold down Ctrl (Control) + Shift and click R. This will refresh the page.

On Safari

• Open the Safari browser.

• Hold down the Ctrl key and press the F5 key to refresh the browser.

On Mozilla Firefox

• Open Mozilla Firefox and Hold down the Ctrl, Shift, and the 'R' keys.

3. Clear Cache

All web browsers store caches and cookies of the websites you have visited. Using this data, the browser loads quickly the next time you visit those websites. But cookies can accumulate over time and can get infected with malware. So, try deleting cache and cookies on your browser. Facebook cannot play video despite a good internet connection. For that:

On Chrome

1. Click on the three dots icon on the top-right corner and go to History > History.

2. Hit Clear browsing data from the left tab and select All time under Time Range.

4. Turn Off Hardware Acceleration

Hardware acceleration is a built-in service that allows some computer services or programs to perform more efficiently. But it can interrupt the normal working of other programs and might be why Facebook videos are not playing correctly in FireFox. So, it’s recommended to disable this feature on your browser while playing Facebook videos. Check out the below instructions to do that:

On Chrome

1. Click on the three dots icon on the top-right corner and go to Settings.

2. Hit Advance at the bottom and navigate the “Use hardware acceleration when available” option.

3. Then, uncheck the “Use hardware acceleration when available” checkbox.

5. Enable JavaScript

If the Facebook videos are not playing even after implementing the solutions mentioned above, the JavaScript is disabled on your browser. In such a scenario, you cannot use some features on a website. Plus, the webpage's functionality is also limited when JavaScript is disabled. Thus, the following workaround is to enable JavaScript by following the below steps:

On Chrome

1. Launch your browser and hit the three dots at the top-right corner.

2. Go to Settings > Privacy and Security > Site Setting. Here, scroll down to Content.

3. Check the “Allow all sites to run JavaScript (Recommended)” box and hit Done.
