Hi, I am trying to change the my email from my mac's default mail to Yahoo mail. However, when I go into Firefox preferences, under actions, to "mailto", there is no option anymore to change it. You either have to use the default mail or pick "use other..." but that takes you to your applications folder to choose an app. I looked on the app store and yahoo charges $2.79 for their app now, it's not free. What am I doing wrong? Help! Thanks.
