In case of sites not using any encryption, the address bar is white.

The address bar turns red when the certificate presented by a secure site has some problems.

Doesn't your browser have search capabilities from the address bar?

And your browser just says, oh, I'm going to display all of this right from the address bar.

I also liked Opera's way of doing search from the address bar.

The name in the address bar looks legitimate, but the site is actually a fake.

It then adds information about the site's security to the address bar.

None of the screen shots show the address bar above the tabs.

On some computers it is located above the address bar.

For example, if you type 77.91.248.30 in the address bar of your browser you'll get the Guardian front page.
