The identity button has been redesigned
As part of the Australis project, the identity button has been redesigned. The favicon has been changed to show an icon describing the connection used:
- The page is served unencrypted (http).

- The page is served encrypted (via https) but some of its content comes from unencrypted servers.

- The page and its content is served encrypted (and the server uses a CV certificate).

- The page and its content is served encrypted (and the server uses an EV certificate).

Also note that the favicon is no more displayed in the address bar.
Australis is a big project to revamp the Firefox interface. The first results will be seen in Firefox 13, some, like this one, should be in Firefox 14 and some other will come later. Stay tuned!
The usual gory details are in the bug.
