First big development. Firefox 3 in out in beta 3. And it has Extended Validation support.
Like Internet Explorer 7, Firefox 3 includes a green-colored bar at the top of the chrome that displays when accessing a site with an EV SSL Certificate. This green bar sits adjacent to the URL and contains the name of the organization and the country. There certainly are some cosmetic differences, like the fact that the organization name is to the left of the domain address in Firefox and to the right in IE7. In the grand scheme of things I don't view these differences as important.
As Firefox moves into release, you can expect me to track milestones and adoption for this browser, just as I have for IE7 and will for any other significant browser that comes out with EV support. And in case you're wondering, IE7 worldwide market share today sits at over 42%.
