Am updated to 63.0 on windows on latest windows. I have Bitdefender on too.Things have worked fie fr a long time but the recent update has screwed things. get following every time I try google or even type aything in the browse bar at the top. uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported. Error code: SEC_ERROR_UNKNOWN_ISSUER

This is plainly rubbish but how do i stop it happening or do I revert to another browser? Nt massively technical so need an easy solution
