Turn Off Your Computer’s Proxy
One way to get around your Firefox browser’s “pr_end_of_file_error” error is by turning off your device’s proxy server. A proxy server transmits your data through a third-party server, causing issues with your connection.
Turning off a proxy server on Windows, Mac, and Firefox is as easy as this.
Disable Proxy on Windows

- Select Network & internet in the left sidebar.
- Choose Proxy on the right pane.
- Turn off the Automatically detect settings option.

- Choose Set up next to Use a proxy server.
- Disable the Use a proxy server option and choose Save.
- Reboot your PC and open your site in Firefox.
Turn Off Proxy on macOS
You’ll deactivate all kinds of proxies on your Mac to resolve the Firefox error.
- Select the Apple logo in your Mac’s top-left corner and choose System Preferences.
- Select Network on the following page.
- Choose Wi-Fi in the left sidebar and select Advanced on the right.
- Open the Proxies tab to view your proxies.
- Turn off all the options in the Select a protocol to configure section and choose OK.
- Restart your Mac and launch your site in Firefox.
Deactivate Proxy in Firefox
Firefox has built-in proxy settings; you can try turning off these proxy connections to resolve your error.
- Open Firefox, select the three horizontal lines in the top-right corner and choose Settings.
- Scroll the page to the bottom and choose Settings in the Network Settings section.
- Choose No proxy on the following page and select OK.

- Close and reopen Firefox, then launch your site.
Disable Your VPN App
VPN apps route your internet data via a proxy server, sometimes causing issues with your internet-enabled apps. Your Firefox error may be the result of a bad VPN service.
In this case, turn off your VPN app, and your issue will be resolved. How you disable your VPN depends on the app you’re using. You’ll find the option to turn off the service on the main interface in most VPN apps. Then, open Firefox and try to launch your site.
If your site launches just fine after disabling the VPN, change your location in the VPN and see if you can then access your site. If that doesn’t work, contact your VPN’s customer support and ask for a resolution. If your issue remains unsolved, you can uninstall your app and get a new one.
Uninstall a VPN App on Windows
- Launch Settings by pressing Windows + I.
- Select Apps in the left sidebar.
- Choose Apps & features on the right pane.
- Select the three dots next to your VPN app and choose Uninstall.

- Select Uninstall in the prompt to confirm your choice.
Remove a VPN App on macOS
- Open a Finder window on your Mac.
- Select Go > Applications in Finder’s menu bar.
- Find the VPN app to delete.
- Drag the app over to Trash.
Turn Off Your Antivirus Software
Sometimes, Firefox displays a “pr_end_of_file_error” error because your antivirus program detected the browser or your site as malicious. In this case, your antivirus will continue to block your access to your item.
You can check for that by temporarily turning off your antivirus protection. How you do this depends on the app you’re using. You can find the option to disable real-time protection on the main screen in most antivirus tools.
If you’re on Windows and use Microsoft Defender Antivirus, you can turn off this tool’s protection as follows:
- Open the Start menu, find Windows Security, and launch the app.
- Select Virus & threat protection on the app’s main page.
- Choose Manage settings under the Virus & threat protection settings header.
- Disable the Real-time protection toggle.

- Select Yes in the User Account Control prompt.
- Quit and relaunch Firefox, then open your site.
Disable DNS over HTTPS to Fix pr_end_of_file_error
DNS over HTTPS is a built-in Firefox option that sends your DNS queries over a secure protocol. Sometimes, this feature doesn’t work well and causes various issues. You can fix that by turning off the option in your browser.
- Open Firefox, select the hamburger menu in the top-right corner and choose Settings.
- Scroll to the bottom and select Settings in the Network Settings section.
- Turn off the Enable DNS over HTTPS option.

- Select OK at the bottom.

When you create a new profile, your browser data, like your bookmarks and saved passwords, aren’t migrated. You should manually back up these items before making and using a new profile.
Export Saved Passwords in Firefox
- Select the hamburger menu in Firefox’s top-right corner and choose Passwords.
