Greetings, This is my first message to the list, so to introduce myself, my name is Alex Faaborg and I am a user experience designer at Mozilla working on our microformats strategy for Firefox. Today Mozilla Labs released a microformat extension for Firefox 2 named Operator. The extension was developed by Michael Kaply at IBM, and detects hCard, hCalendar, geo, hReview and rel-tag. You can read more about the extension on the Mozilla Labs blog: http://labs.mozilla.com/2006/12/introducing-operator And you can download Operator here: https://addons.mozilla.org/firefox/4106/ Cheers, -Alex
