Outdated: Visiting an "https" Web Site with Firefox 18
This section describes how Firefox 18 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 18, 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 18 to visit the Facebook log in page: "https://www.facebook.com":
If you click the lock icon, Firefox will provide you a summary of security related information about this Web site. For https://www.facebook.com Web site, you will get something like:
You are connected to "facebook.com" which is run by (unknown) Verified by: VeriSign Trust Network Your connection to this website is encrypted to prevent eavesdropping. [More Information...]
