Revision Content
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 green padlockgray padlock.
However, in rare cases, it may also be a gray padlock with a yellow warning triangle or a padlock with a red strike over it .

Green padlock
A green padlock (with or without an organization name) indicates that:
- You’re definitely connected to the website whose address is shown in the address bar and the connection hasn’t been intercepted.
- The connection between Firefox and the website is encrypted to prevent eavesdropping.
A green padlock plus the name of the company or organization, also in green, means this website is using an Extended Validation (EV) certificate. An EV certificate is a special type of site certificate that requires a significantly more rigorous identity verification process than other types of certificates.
For sites using EV certificates, the Site Identity button displays both a green padlock and the legal company or organization name and location of the owner of the website, so you know who is operating it.
Gray padlock
A gray padlock (with or without an organization name) indicates that:
- You’re definitely connected to the website whose address is shown in the address bar and the connection hasn’t been intercepted.
- The connection between Firefox and the website is encrypted to prevent eavesdropping.
A gray padlock means this website is using an Extended Validation (EV) certificate. An EV certificate is a special type of site certificate that requires a significantly more rigorous identity verification process than other types of certificates.
For sites using EV certificates, the Site Identity button displays a gray padlock, as well as the legal company or organization name and location of the owner of the website when you click the button so that you know who is operating it. See Content Blocking for additional information about what displays when clicking the button.
Gray padlock with yellow warning triangle
A gray padlock with a yellow warning triangle indicates that the connection between Firefox and the website is only partially encrypted and doesn't prevent eavesdropping. This also appears on websites with self-signed certificates or certificates that aren’t issued by a trusted authority.
For information about what "partially encrypted" means, see Mixed content blocking in Firefox. This is a problem the site developer needs to resolve.
Gray padlock with a red strike over it
A padlock with a red strike over it indicates that the connection between Firefox and the website is only partially encrypted and doesn’t prevent against eavesdropping or man-in-the-middle attacks.
This icon will not appear unless you’ve manually deactivated mixed content blocking.
