Viewing Server Certificate Path in Mozilla Firefox

This section provides a tutorial example on how to view certificate path when visiting a 'https' Website in Mozilla Firefox. The top certificate in a certificate path is the root CA certificate, which is trusted automatically.

When a browser validates a server certificate, it will try to build a certificate path - an ordered list of certificates that satisfy these conditions:

Here is what I did to see the certificate path for https://login.yahoo.com Website on Mozilla Firefox.

1. Visit https://login.yahoo.com with Mozilla Firefox, and view the server certificate again.

2. Click the "Details" tab on the Certificate Viewer. A certificate path with 3 certificates shows up in the Certificate Hierarchy section:

DigiCert High Assurance EV Root CA         - Root CA certificate
 |- DigiCert SHA2 High Assurance Server CA - Intermediate CA certificate
     |- *.login.yahoo.com                  - Web server certificate

3. Click on "DigiCert High Assurance EV Root CA" in the path to see more about this root CA certificate.

4. Click on "DigiCert SHA2 High Assurance Server CA" in the path to see more about this intermediate CA certificate

5. Click on "*.login.yahoo.com" in the path. to see more about this HTTPS Web server certificate.

What do you think about this certificate path? Should we trust login.yahoo.com now? I think this is a valid certificate path and we should trust login.yahoo.com, because:

The picture below shows an example of a certificate path:
