whenever I go to an https site, I get this error message. My other browsers are not having the same issue. I deleted cert8.db as one site suggested. Stopped using firefox due to this issue. example: www.comcast.net, once I sign into email, I get this error message. Amazon.com - same issue. So, these are very common sites. This only started in past two weeks.

Oops. Spoke too soon. It was working because I was connecting through my home network connection. When I'm at work, the issue is still present.

Check out why the site is untrusted (see the Technical details) and if this is caused by a missing intermediate certificate then see if you can install this intermediate certificate from another source.

Some firewalls monitor secure (https) connections and send their own certificate instead of the website's certificate.

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.
