CreditCardNanny is an extension that detects forms that otherwise look secure - proper and valid SSL certificate, encrypted and seemingly safe enough to enter sensitive data such as credit card details - but actually then submit this form data in a cleartext email to the site administrators!

This extension detects such forms and warns you of the possibility that sensitive information may be exposed in clear-text, putting you and your sensitive data at risk.

You can test the extension by browsing to https://cc-nanny.appspot.com/test-secure-page - a dummy credit card form that uses a form emailer script - a very common pattern used on an alarmingly large number of websites.
