Backing up Comodo Personal Certificate from Firefox

This section provides a tutorial example on how to backup a personal certification with a private key from Firefox to an external file in PKCS12 format and with password protection.

After installing and viewing my personal certificate in Firefox, I need to create a backup copy and keep it separately in a secure place:

1. Open the Certificate Manager in Firefox as described in the previous tutorial.

2. Click the "Your Certificates" tab. I see my personal certificate listed under "COMODO CA Limited".

3. Select my certificate and click "Backup..." button. The save file dialog box shows up.

4. Enter find a folder, enter a file name like "MyPrivateKeyCert.p12", and keep "PKCS12" as the file type.

5. Click "Save" button. The certificate backup password dialog box shows.

6. Enter a new password and click "OK". My personal certificate is backed up to a file now.

Here is my understanding of what happened:
