www.facebook.com 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

I tried everything on forum. There is no add exception button. this problem also exist in chrome and IE. FB, Twitter, youtube, linkedin all shows the error. Using VPN solves the problem a little. HOWEVER All other computers in same network work just fine.

PLEASE HELP..

You can click the "Advanced" button to expand this section and show extra details. If the certificate is not trusted because no issuer chain was provided (SEC_ERROR_UNKNOWN_ISSUER) then click the blue error message to expand this section and show the certificate chain. Please click "Copy text to clipboard" and paste this base64 encoded certificate chain text in a reply. That will allow us to check details like the issuer of the certificate.

The certificate is issued by Cisco Umbrella.

Do you have security software or content filtering software that intercepts the connection or use a VPN?

The last certificate in the chain links to Cisco Umbrella Root CA. You do not have this root certificate installed

No I dont have security software or content filtering software that intercepts the connection. I have Vpn plugin with firefox(use when needed).

What should I do now?
