5 Ways to Fix the Mozilla Firefox SSL Connection Error

The ‘Secure Connection Failed’ or the SSL connection error is a warning message that can appear when you try to open a website in Mozilla Firefox over a safe connection. When it occurs, a tab appears with the ssl_error_rx_record_too_long error code on your browser screen, and your Mozilla Firefox stopped working. It happens when your Firefox browser is unable to confirm the secure data because of an incorrectly configured SSL certificate. On that condition, you can follow these troubleshooting ways to get rid of the SSL error.

Solution 1 – Replace the Website URL with the HTTP Protocol

You can try this simple solution to solve the issues. To apply it, you have to open your site URL with HTTP instead of the HTTPS. Open a new tab and then insert the URL of the site that starts with http:// instead of the https://.

Solution 2 - Run Firefox in Safe Mode

You can run your Firefox browser in Safe Mode to solve different browser-related problems, including the SSL connection error the as well. This process will disable the hardware acceleration and add-ons and restore the Firefox program to its default settings temporarily. By doing that, you may be able to open the website that can’t otherwise run in Firefox normal mode. To do so, you can go to the Help section of your browser.

Solution 3– Disable Proxy Setting

If your website does open in Firefox’s Safe Mode, then you no longer require doing anything. However, if you still get the ssl_error_rx_record_too_long error when opening browser without the Safe Mode, then try to fix the SSL error code by disabling the proxy settings if you don’t require any configuration. To do so, open the connection settings of your Firefox browser and then turn off that setting. Here’s how to do:

1. Click the ‘Open’ menu and choose the ‘Options’ submenu.
2. Click the ‘Advanced’ heading on the left of the Options menu.
3. Choose the ‘Network’ option to open the alternate options.
4. Click the ‘Settings’ icon to access the ‘Connection Settings’ screen.
5. Choose the ‘No Proxy’ option if Firefox is set up with additional proxy settings.
6. Click the ‘OK’ button and restart your Firefox browser.

Solution 4 – Turn off Firefox plug-ins

If you’re still unable to open the website in your Firefox browser and are getting the SSL connection error, some of the add-ons connected to the Internet servers are probably encountering the problems. To get rid of this error, you can turn off add-ons in Firefox. Here’s how to do:

1. Click the ‘Open’ menu, and then the Open Help Menu when you’re running the browser in Safe Mode.
2. Choose the option reads like ‘Restart with Add-ons Enabled.’ Input the ‘about: addons’ in your browser URL bar. Click the ‘Enter’ button.
3. Turn off the add-ons by clicking the ‘Disable’ button next to each add-on.
4. Restart the Firefox, and then try opening the website again.

Solution 5 - Reset the Firefox

Restoring your web browser to its default theme is always the best way to solve different browser problems. It will delete several custom settings you have configured in Mozilla Firefox and remove themes and all installed add-ons. You can refresh it by following these steps:

1. Input the ‘about: support’ in the browser’s address bar and hit the Enter key. It opens up the troubleshooting information page tab.
2. Click the Refresh Firefox button, and then click the ‘Refresh’ option to confirm the action.
