Viewing Server Certificate in Mozilla Firefox
This section provides a tutorial example on how to view certificate when visiting an 'https' Website in Mozilla Firefox.
When you visit a "https" Web server, it will send its certificate to your browser.
Server's certificate is needed by the browser for these 2 tasks:
- Your browser must validate the certificate to determine that the Website can be trusted or not before doing any further communications.
- Your browser must use the public key in the certificate to help secure the communication messages sent and received.
Normally, your browser will do these 2 tasks automatically without your interaction.
You don't need to know where is the server certificate and what's in the certificate.
But since I am interested to learn more about "https" communication,
I want to see the server certificate.
Here is what did on Mozilla Firefox to see details of the server certificate.
1. Run Mozilla Firefox and go to https://login.yahoo.com and wait for the log in page to be displayed.
2. Click the lock icon at right side of the web address.
The page security information message box shows up
3. Click on right array at the end of "Secure Connection" line.
The Website security information shows up.
4. Click the "More Information..." button at the bottom.
The security detail dialog box shows up.
5. Click the "View Certificate" button.
The Certificate Viewer dialog box shows up.
Cool. Now I see a real server certificate for commercial uses.
The picture below shows you steps to see the certificate:
