What is pr_connect_reset_error?

The pr_connect_reset_error indicates that the browser cannot connect to the server. It generally happens when a client or browser sends a request to the server, but the server declines before completing the request.

At the Front end, this error may seem similar to other connection errors, which you might find in the 4XX and 5XX range of status codes. But this particular pr_connect_reset_error is generally shown in the Firefox browser.

This connection error can be triggered by various reasons, including internet issues, server problems, and network configuration issues, among others. We will explore these in detail in the later sections.

1. Check your network connection

Since the pr_connect_reset_error is a connection error, the first thing you need to check is whether your internet connection is stable or not.

For example, if you are using a Wi-Fi connection for internet access, try moving closer to the router range, accessing the other websites, or connecting to the internet directly via ethernet cable.

In case you are using any VPN services or proxy, disable it for a while and check whether it fixes the error or not.

2. Change your network connection

Sometimes even a simple solution can indeed do wonders for complex problems. While referring to this particular error “pr_connect_reset_error”, it can also be possible that your current network for some reason is not allowing you to access your favorite website.

To check if this is the main culprit, try switching to a different network. For example, if you are connected to a Wi-fi try switching to the mobile network instead. If this solves the issue, it might be your Wifi problem. Immediately contact your ISP and intimate the same.

3. Clear Firefox Browser Cache

Since the pr_connect_reset_error is commonly seen in the Firefox browser, you need to clear its cache. Your cache generally contains important files and settings of the websites that you visit often. And to bring the best user experience, browsers tend to fetch data from the cache.

Unfortunately, sometimes these caches get outdated or corrupted resulting in displaying such “pr_connect_reset_error” messages on the screen.

The best thing you can do is to clear the cache and try to visit the website again.

To do this follow these simple steps given below.

• First, you need to open your Firefox web browser and navigate to its top-right corner. Click on Menu option > Library >History > Clear recent history.

• Now select a time range on the pop that will appear. If you want to clear all the cache data. you need to select the “Everything” option. Now click on the Details section and choose the type of data you want to clean (Browsing, download history, or Cache).

• After finalizing the selections, finally, click on the Clear Now button. Now you have successfully been able to clear all the cache from your browser.

4. Deactivate Firefox extensions

Although it might not be an essential step to deactivate Firefox extensions or add-ons. But you don’t want to give the browser a single excuse to display this error. It is because sometimes, these extensions or addons are poorly coded conflicting with the network and triggering such error messages.

Here are the steps you need to follow:

Go to your Firefox browser > click on the Hamburger menu > select Add-ons and themes.

Use the toggle switches to deactivate or disable the extensions.

Now, Check whether the PR_CONNECT_RESET_ERROR is still showing up by accessing the website. If the error is not showing up, it means there is a faulty extension that was the culprit.

To figure that out, toggle on each extension one by one > and refresh the site each time.
