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.
Thunderbird has its own security certificate manager. It does not use the certificates stored in the operating system. Here is how to access and use Thunderbird certificate manager.
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.
