Outdated: Viewing Server Certificate in Firefox 35
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:
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:
You are connected to yahoo.com Verified by: VeriSign, Inc. The connection to this website is secure.
3. Click the "More Information..." button on the message box. The Page Info dialog box shows up displaying the "Security" tab.
4. 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:
