Even picking the 'obvious' secure methods here give you good information. If you feel you 'stay secure' as far as privacy, then give it to someone who still doesn't have a clue! Without intending, friends and family can blow the privacy you feel you have out of the water. Clue them in! http://www.aclu.org/privacyquiz/
Not working in Firefox for me either, not that I'd trust what the ACLU thinks about privacy anyway. They're more about the rights of the select few than the whole.
It is also a bit more of a quiz for the mainstream citizen. For example they ask if you lookup health problems on the internet, if you answer yes your risk automatically goes up because they assume you're using Google which has a database available to the government and not some alternate search provider who stores no logs and has SSL.
It only renders properly for me in Firefox if I allow the Omniture tracking javascript to run. No comment.
