Secure Connection Failed An error occurred during a connection to www.google.com. SSL peer was not expecting a handshake message it received. Error code: SSL_ERROR_HANDSHAKE_UNEXPECTED_ALERT The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem.

This is happening to literally anything related to Google. Be it gmail, google forms, google docs etc. If I wait for 10-15mins then it starts working. Then after some time again this problem persists. This happening only in Firefox and not Chrome or related browsers like Brave. So what is the problem?

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
