Well of course he uses Firefox. As the head of security for M$ he had darn well better know the competition. Without using the other products how is he supposed to do his job better? I bet he has nearly every possible browser available and surfs with them jst to see how he can improve IE. In fact I will bet he also runs Linux occasionally too so he can see what they have done to outpace M$. Publicly speaking he probably should not have said what he did but I will not fault him for using Firefox...only for continuing to let IE be an insecure browser.

My thoughts there exactly, sigmazeta314. Well said. :)
