I've searched extensively with no luck on finding a correct answer. Simply, how can I make my (.msn) hotmail email address the default firefox mailto address?


all I want to do is have my .msn (hotmail) e-mail addy used for sending e-mails from firefox. I've tried to use the about:config stuff I've found and it doesn't work, even when I change the settings in both the gecko and URL lines. Nothing happens (no drop down "add application" menu)

Someone please help in simple, step-by-step instructions. I have a mac OS-X running Firefox 15.0. HELP !!!!
