How to fix connection reset error in Firefox
The connection reset error is a website connection error that occurs in Firefox. It’s an error that arises when some users try to open certain websites in Firefox; that error displays a message that says, “An error occurred during a connection to <page URL> PR_CONNECT_RESET_ERROR.”
Consequently, Firefox doesn’t open websites for which this error occurs. The issue means Firefox can’t make a connection to a site’s server. Its error message appears because the browser couldn’t verify the data received.
How to fix connection reset error in Firefox
- Change Network Settings in Firefox
First, try changing how Firefox connects with sites. You can do that by adjusting some network settings in Firefox as follows:
- Input about:preferences#general in Firefox’s URL bar, and press the Return keyboard key.
- Scroll down the General tab and click Settings.
- Select the Auto-detect proxy settings for this network radio button.
- Then click the Enable DNS over HTTPS checkbox to enable that setting.
- Select OK to save the new network settings.
- Clear Firefox Cache
Corrupted or outdated browser cache data can cause issues for opening web pages. So, clearing Firefox’s cache could feasibly fix the PR_CONNECT_RESET_ERROR for some users. You can clear out Firefox’s cache through the browser’s settings.
- Disable Add-ons for Firefox
Some Firefox users have confirmed that disabling extensions can resolve the PR_CONNECT_RESET_ERROR. Honey and DuckDuckGo are two add-ons cited to cause the error, but other security extensions could also feasibly cause the issue to arise.
- Disable Proxy Server
The PR_CONNECT_RESET_ERROR issue can occur because of a proxy server intermediary between the client and server. If you have a proxy server enabled on your PC, that could be causing connection issues with certain sites.
- Disable VPN Software
Are you using a VPN (Virtual Private Network) connection? If so, try disabling your VPN software, for it could be the case that the filtered VPN connection is causing the PR_CONNECT_RESET_ERROR. Some sites (particularly those of streaming services) block users from opening them with VPN software.
- Disable IPv6 in Firefox
The IPv6 protocol Firefox supports can cause website connection issues on some PCs. Some Mozilla Firefox users have also said disabling IPv6 fixed the PR_CONNECT_RESET_ERROR for them.
- Disable Windows Defender Firewall
Windows also has a default firewall that filters network traffic and can wrongly restrict access to certain websites. So, that’s another security feature that can also block Firefox from connecting to sites and cause the PR_CONNECT_RESET_ERROR issue.
