I am constantly getting This Connection is Untrusted (Error code: ssl_error_bad_cert_domain). At the moment it says that google is receiving a facebook certificate. It constantly bothers me and it happens frequently and randomly. It happens and then go away after a short amount of time. If I add an exception, I can't access google at all and will always be re-directed to facebook. I don't know how to fix this stupid error.

You can retrieve the certificate and check details like who issued certificates and expiration dates of certificates.

  • Click the link at the bottom of the error page: "I Understand the Risks"

Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".

  • Click the "View..." button and inspect the certificate and check who is the issuer.

You can see more Details like intermediate certificates that are used in the Details pane.


Create a new profile as a test to check if your current profile is causing the problems.

See "Creating a profile":

If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.
