Hello sir/madam, Two days earlier my system's date and time changed automatically so I replace CMOs battery and from that day when I try open google.com and mail.zoho.com it is showing "secure connection failed" - the page you are trying to view cant be shown becoz the authenticity of the received data could not be verified. I tried to reset firefox but no success. I am not able to find a rootcause for this issue and is it because of time date or any other browser fault or antivirus protection? i am facing this issue since last 5days I am using firefox 63.0.3(32-bit) Please request you to help me asap. I tried to open same website in chrome also but it is giving same alert message.
