4: Test your Firefox browser

Sometimes ‘Secure Connection Failed’ error may occur on Firefox if Firefox finds the website to be dangerous or untrustworthy. That is why Firefox browser testing is so critical. If Firefox approves the website, it means that there’s a problem in the SSL connection.

SSL (Secure Socket Layer) is a cryptographic protocol that allows users to communicate securely over the internet. A website that uses HTTPS:// at the starting of its URL is said to be a secured website. When Firefox doesn’t find a website secure, it will trigger an error displaying “Secure Connection Failed”.
