Visiting an "https" Web Site with Firefox
This section describes how Firefox shows a lock icon when you visit an 'https' Web site to provide you more security related information.
As we learned in the previous chapter, if a Web site wants to encrypt communication messages with your browser, it will enable the SSL protocol and use "https" as part of their Web address.
If you go to a Web site that provides online services, I am sure that you will see "https" in the Web address field starting on the log in page. This indicates that Web site uses SSL protocol to encrypt all information you send and receive on this server.
If you are using Firefox 69, it will display an extra lock icon in front of the Web address field when you are visiting an "https" Web site. The picture below shows the "https" Web address and the lock icon when you use Firefox to visit the Facebook log in page: "https://www.facebook.com":
If you click the lock icon, Firefox will provide you the Web site information including connection security.
Click the ">" on the "Connection" line, the certificate verification status shows up:
www.facebook.com Secure Connection Verified by: DigCert Inc
More security related information will be provided if you click the "More Information" button. See next sections.
