Site Information panel

The Site Information panel opens when you click the padlock in the address bar. (On secure connection error and certificate warning pages, you'll see an "i" icon instead of a padlock.) This is where you can view information about connection security and site identity, and make choices about any site permissions you have allowed or blocked.

This panel also includes a More Information button that will open the Page Info window Security tab for the website.
