Mozilla Firefox and Google Chrome are some of the best and most widely used web browsers on the market.

While there are other feature-rich browsers, users still prefer either Google Chrome or Mozilla Firefox for their robust performance and simple-to-use features.

One of the common things between most web browsers is the errors that you would come across.

Notably, several Mozilla Firefox and Google Chrome users have reported coming across PR_CONNECT_RESET_ERROR.

This could be annoying since it comes out of nowhere and people have no idea what triggers the PR_CONNECT_RESET_ERROR on Google Chrome or Firefox.

If you are also one of such users and are looking for solutions to fix the error, then you have landed in the right place.

Because in this guide, we will give you 5 of the best solutions that have helped users tackle the PR_CONNECT_RESET_ERROR on both browsers and get back to web browsing. Let us check it out.


When a browser fails to connect to a server, then you would come across multiple errors one of which is the PR_CONNECT_RESET_ERROR.

While it may seem like it is your regular connection error such as error 400 or 500, the error is mainly shown in Mozilla Firefox.

In other browsers, such as Google Chrome, or other browser based on Chromium, such as Microsoft Edge, Opera, and Brave, you will see the same error as ERR_CONNECTION_RESET.

Both errors are the same and Chrome and Firefox users have reportedly complained about coming across this problem.

After some research, we have found a list of probable reasons that would trigger the PR_CONNECT_RESET_ERROR on Chrome or Firefox:

  • There must be some firewall or other security issue
  • You might be trying to access content that is restricted in your geography
  • There might be some extensions that could be conflicting with the browser
  • There could be an error with the VPN that you are using
  • TCP Protocol filtering can also trigger this problem
  • A corrupt browser cache is also the root cause of many problems

Now that you know about the possible reasons for this PR_CONNECT_RESET_ERROR, let us check out the solutions to fix it.

We have explained the steps for Windows Defender Firewall. But if you have installed a third-party antivirus software then you can open it and disable the program and check if this fixes the PR_CONNECT_RESET_ERROR or not.

Also, if you are confused about which antivirus software to go for, you can refer to our guide which lists some of the best antivirus software that you can select for your Windows PC.

3. Disable VPN

If you are using a VPN of any sort then you should try disabling them and check if this PR_CONNECT_RESET_ERROR or not.

Notably, we use a VPN in order to hide our IP address and online whereabouts as well as access the restricted content that is not available in your region.

However, often VPN apps can conflict with the web browser server route and cause multiple issues, one of which is the problem at hand. Disable the VPN and check if this fixes the issue or not.

4. Disable extensions

If you are using extensions on your Firefox or Chrome browser, which you might be to enhance the features, then you might want to check in on them and try disabling them to see if this fixes the issue or not.


  1. Open the Mozilla Firefox browser.
  2. Click on the Menu.
  3. Select Add-ons.
  4. Select the unwanted extension and click Remove.


  1. Launch Chrome.
  2. Click on the Menu icon.
  3. Navigate to More tools > Extensions.
  4. Simply toggle off the extensions.

5. Connect to a different network

Well in most cases the issue is resolved by one of the above solutions. However, if you are still not able to resolve the problem then you could try using a different network.

While this solution may not seem that appropriate for specific settings, it could be at least good enough to tell you if your router or network is experiencing some issues.

6. Change your browser (Bonus tip)

As a last resort, if none of the above solutions fixed the problem for you, then it is time for you to either permanently or temporarily switch to a different web browser.

There are a bunch of Chromium browsers, that bring the same feature set as Google Chrome such as Brave, Vivaldi, etc. So, you can try them out. Moreover, we would recommend you use the Opera browser, because of the fast speed, reliability, and features that it offers.

Can the firewall block my browser?

A firewall literally acts as a wall between your browser and the malicious content that is trying to enter your PC via your browser.

It protects you from everything malicious that would hamper your overall user experience. A firewall blocks everything suspicious, so there is a high chance that your firewall is blocking your browser.

That is it from us in this guide. Let us know in the comments below which one of the above solutions fixed the PR_CONNECT_RESET_ERROR or not.
