Previously secure web pages now missing the padlock, and the address bar now shows "about: blank". I'm concerned that security is compromised. How does one fix the "about:blank" problem as antivirus scanning does not help?

In Firefox 4 you no longer have the Status bar that showed the padlock in previous Firefox versions.
The padlock only shows that there is a secure connection and doesn't guarantee that you are connected to the right server.
So you might still be connected to the wrong server if you make a typo in the URL and someone has claimed that mistyped URL.
The functionality of the padlock has been replaced by the How do I tell if my connection to a website is secure? on the left end of the location bar.
