Manage Security Certificates on Thunderbird

This section provides a tutorial example on how to access and use Mozilla Thunderbird Certificate Manager, which stores certificates for different application purposes.

1. Click "Settings > Privacy and security > Manage certificate". You see the "Certificate Manager" window.

2. Review entries in each tab:

3. If you created or received a certificate, select the tab that matches the certificate type, and click "Import" to load the certificate into Thunderbird.

4. If you load a certificate into a wrong tab, you will receive an error message. For example,

Alert
This is not a certificate authority certificate, so it can't be
imported into the certificate authority list.

5. Select a certificate and click "View" to see details of the selected certificate.

6. Select a certificate and click "Export" to export the selected certificate into a certificate file.

7. Select a certificate and click "Edit Trust" to change the trust options.
