How To Fix “Secure Connection Failed” Error In Mozilla Firefox Browser


Are you having problem accessing some specific website (those that begins with https)? If you are, then it might interest you to know that some websites try using out-dated (no longer secure) TLS mechanisms in an attempt to secure your connection. Firefox protects you by preventing navigation to such sites if there is a problem in securely establishing a connection. When this happens, you will see an error page just like the one displayed in the image below with the option to report the error to Mozilla.

When you are faced with this issue and you want the error message to stop appearing, just follow the steps below to automatically get rid of the Secure Connection Failed message and access secured sites whose TLS are already out-dated.

Solution to “Secure Connection Failed” Message:

Open the browser and type in about:config in the address bar and press Enter.

Secure Connection1

On the warning page that will appear, click on “ I’ll be careful, I promise!”.

Restart Firefox and enjoy visiting secured sites whose TLS is out-dated without the Secured Connection Failed message displaying.
