I want to use Windows Mail as my default e-mail program when using Firefox to browse the internet and initiate e-mail messages. How can I get Firefox to use Windows Mail? Right now, it is using Thunderbird, which I do not even have installed on my PC, and it is using the web e-mail Address Book and Sent folder on my ISP's web site, rather than being able to reference the Address Book and Sent folder on my PC.

Thank you!
