https security button in Safari 6.0.2
I happened to notice today that the https security button, which is supposed to display in the address/search field whenever one has gone to a secure website, is absent. At least when I'm browsing in a "standard" guest user account. Browsing while logged in under the admin account, the button is present when it should be. For example, my home button in Safari goes to https://www.google.com/ When I click on that and the google home page comes up, on the guest account, there's no gray https button in the address field, but on the admin account there is.
My impression is that the link is NOT secure as long as the button is not displayed (per http://support.apple.com/kb/PH11947), so what might have gone wrong, and how can I fix it?
Advance thanks.
