secure https padlock lock grey

Firefox uses a padlock icon next to a website's URL to let you know your connection is encrypted. Click on the icon for more information.

The Site Identity button (a padlock) appears in your address bar when you visit a secure website. You can quickly find out if the connection to the website you are viewing is encrypted, and in some cases who owns the website. This should help you avoid malicious websites that are trying to obtain your personal information. The Site Identity button is in the address bar to the left of the web address. Most commonly, when viewing a secure website, the Site Identity button will be a {for not fx70}green padlock{/for}{for not fx70}[[Image:green lock 42]]{/for}{for fx70}gray padlock{/for}{for fx70}[[Image:Gray padlock - Firefox 70]]{/for}.
