You’ll be back to surfing the web in no time

Mozilla Firefox’s “pr_connect_reset_error”makes your sites inaccessible, causing a huge inconvenience. If you continue to get this error and aren’t interested in switching your web browser, you can follow a few methods to resolve your issue. Here’s how.

Often, your network or browser’s minor bug causes the above-mentioned problem. Other reasons include your firewall blocking your site connection, having a non-working proxy set up on your machine, and so on.

Clear Your Cache in Firefox

The easiest way to fix the “pr_connect_reset_error” is to clear your browser’s cache. Doing so deletes the images and other files that the Firefox browser has cached, fixing problems with these files.

When youclear your cached web content, you don’t lose your saved logins, cookies, and other site information.

Use a Different Network to Fix pr_connect_reset_error

A valid reason you can’t access a site is because your network prohibits that particular site on the network. Various factors cause your internet service provider (ISP) to add a site to the block list.

You can verify that by switching to another internet network and checking if the site loads. For example, you canswitch to your phone’s hotspotif you’re currently on your home Wi-Fi network and see if your site opens.

If your site launches without issues on the alternative network, talk to your ISP and see what the problem is.

Uninstall Your Third-Party Firewall App

Third-party firewalls often don’t work well with many installed apps, including Firefox. Your firewall app may have detected Firefox or your sites as malicious items, restricting your access to those items.

While you can whitelist Firefox and your sites in your firewall app, if that doesn’t work, uninstall the app from your PC as follows.

Disable Windows Firewall to Fix the Secure Connection Failed Error

Even if you don’thave a third-party firewall installed, your Windows PC’s default Windows firewall may be active in the background. You can disable this firewall and see if your sites then open.

Turn Off Your Antivirus Software

One reason youcan’t access your site in Firefoxis that your installed antivirus program has detected your browser or your site as a suspicious item. In this case, temporarily turn off your antivirus protection and see if your site loads.

How you disable the protection varies by antivirus program. You can turn off the Microsoft Defender Antivirus protection as follows:

Turn Off Your Proxy

When you experience network errors like “pr_connect_reset_error,” it’s a good idea to disableyour machine’s main proxyas well as the proxy within the app in question. That should resolve your problem if it was caused by a bad proxy server.

You can turn off your PC and Firefox’s proxy features as follows:

Now that your proxy is disabled, launch Firefox and try to access your site.

Disable Your VPN Service

When it comes to network-related activities, VPNs play a huge role. These services route your internet traffic via a middle server, allowing you to bypass your ISP’s restrictions.

However, those features sometimes come at a cost. Your “pr_connect_reset_error” may have resulted from a poorly configured VPN. In this case, temporarily turn off your VPN service and see if your sites launch then. Most VPN clients have a huge toggle button on their main interface, allowing you to enable and disable the service.

If your sites load after deactivating the VPN, you may want to speak to your VPN provider to find a solution.

Turn Off Firefox’s Add-ons

Add-ons add extra features to Firefox, letting you get more out of this browser app. Sometimes, one or more of the installed add-ons interfere with the browser’s core functionalities, causing various problems.

In your case, you can turn off all your Firefox add-ons and see if that resolves the issue. If it does, you can remove the problematic add-ons and keep the good ones.
