The Firefox browser has several privacy and security advantages, among other features. But when YouTube stops working on Firefox, it can ruin the overall browsing experience. You may encounter an ‘Error occurred please try again‘ message or random crashing issues while playing YouTube videos. 

It may occur when your computer’s internet connection is slow. Likewise, an outdated Firefox browser may also hinder the working of YouTube. 

So, without further delay, let’s check out the detailed explanation of fixes to resolve the issue at hand. 

Why is Youtube Not Working on Firefox Only?

Here are some of the probable reasons for the issue:

  • Poor internet connection
  • Corrupted or overloaded cache Firefox data
  • Firefox is outdated.
  • Outdated YouTube’s cookies
  • Outdated plugins

How to Fix YouTube Not Working on Firefox?

If YouTube is not working on Firefox, you may start by refreshing the YouTube page. Likely, closing down the browser and re-launching can also help. 

After trying some general methods, you can check the internet connection and use another Wi-Fi network if you still face the issue. Also, restarting the networking device can also be fruitful. 

You can check out the guide below for a detailed description of the fixes. 

Recheck Your Internet


Since you are using YouTube on the Firefox browser, one of the key components that should work well is the internet connection. 

So, you need a stable internet connection for the proper working of YouTube. If your current Wi-Fi network is giving you trouble, try switching to another Wi-Fi connection. You can also use an ethernet cable for better connectivity. 

Restart the Wi-Fi Router


Sometimes the network issue with your networking device can also cause the problem. In such a case restarting the Wi-Fi router and executing a power cycle can be the ideal solution. For that, unplug the power adapter from the router and wait for some time. Then, plug the adapter in and start the router. Check if this solves your problem or not.
