Windows Live Mail help - email links not working.

I’m new to Windows 7 and I am having an issue with the included Windows Live Mail client. When I click on a link in a received email, rather than the linked page opening in my Firefox browser, like with XP and Outlook Express, I get an error message which says: There was an error sending the message to the program. Is it possible to configure Windows Live Mail to open the link in my Firefox browser or do I now have to cut and paste the link each time?
