I have been waiting for Microsoft to support Firefox in their Live products. Windows Live Mail is a pretty good web app, but without Firefox support, it kinda left me out in the cold. I do use the Firefox IE Tab plugin, which usually works with Windows Live Mail, but I would much rather have a native Firefox support. Also, I think I need to mention the significance of Microsoft's smarts here. By allowing Firefox users in, they are going to gain a much bigger audience than if they didn't add support. Allowing both browsers to work with their site takes a little extra time to code, but it will benefit the initiative in the long run. I think Windows Live Mail is great, and it has become a decent "online outlook" that is easy to use and helps you organize mail by dragging and dropping items. It is pretty slick.
