How to Resolve 'Secure Connection Failed' Error in Firefox?

more options

I’m encountering a persistent issue while browsing certain websites in Firefox where I consistently receive a 'Secure Connection Failed' error message. This issue disrupts my browsing experience and I’m keen to understand how I can troubleshoot and resolve this error effectively.

I’ve already checked my internet connection and confirmed that other browsers do not encounter the same issue. Additionally, I’ve ensured that my system’s date and time settings are accurate. Despite these steps, the problem persists specifically within Firefox.

Could someone please provide detailed steps or insights on how to diagnose and fix the 'Secure Connection Failed' error? I’m particularly interested in understanding how Firefox handles SSL/TLS connections and any specific settings or configurations within Firefox that could affect this error.

Your assistance in resolving this matter would be greatly appreciated. Thank you!
