'Your Connection is Not Secure' is a common SSL error, often in the form of SEC_ERROR_UNKNOWN_ISSUER (this code snippet appears in the error message) on Firefox. Secure Socket Layers (SSL) is a network security protocol widely used by banks, social media communication tools, and e-commerce sites to safeguard personal and financial information of customers from leakage.
If a website uses an SSL certificate, its URL will start with HTTPS (Hypertext Transfer Protocol Secure), replacing the standard HTTP. This means that all information sent or received through the website using the secure network protocol is encrypted.
Sadly, mainstream websites using SSL certificates like Facebook, Twitter, Paypal, or eBay are at risk of being blocked by the 'Your Connection is Not Secure' or SEC_ERROR_UNKNOWN_ISSUER error messages.
However, if you intend to visit an unfamiliar website, we advise against dismissing the 'Your Connection is Not Secure' warning. The website might harbor malicious software or other unsafe content, after all!
In the case of being unable to access legitimate domains you've previously visited, the issue could lie in one of the following errors:
Incorrect date and time settings;
Use of a fake SSL certificate;
Incorrect SSL certificate;
Domain containing harmful content;
Unlawful SSL certificate provider;
Third-party antivirus programs or Windows firewall blocking site access;
Browser malfunction or expired usage.
For each scenario, there exists a distinct method to troubleshoot SSL issues on Firefox. For detailed guidance, refer to the SSL troubleshooting guide on Firefox here.
