Visiting "https" Website with Mozilla Firefox

This section describes how Mozilla Firefox shows a lock icon when you visit an 'https' Website to provide you more security related information.

As I mentioned earlier in the book, Web browsers play very important roles in using HTTPS (Hypertext Transfer Protocol Secure) to secure Web communications. Now let's see how Mozilla Firefox, as the leading Web browser, supports HTTPS.

1. Run Mozilla Firefox and go to Yahoo home page, www.yahoo.com.

2. Click "Mail" in the Yahoo Sites menu.

3. After Mozilla Firefox finishing displaying the login page, look at the bottom right corner of the browser window. You will see lock icon displayed next to the address:

Lock Icon on https Address - Mozilla Firefox
Mozilla Firefox Showing Lock Icon on HTTPS Address

What happened here was:

The lock icon at the right side of the address indicates that this page is secured with HTTPS. If you click the lock icon, Firefox will provide you more security related information for this page. See next sections for more tutorials.
