I have Firefox and iTunes 7.5 and I got a link from an Apple Music newsletter that was supposed to open iTunes via Firefox. It normally did this pretty easily when I had an earlier version of Firefox, but this time when I clicked the link, Firefox sent me a message saying

"Firefox doesn't know how to open this address, because the protocol (itms) isn't associated with any program."

I was wondering if there was a way to associate the link with iTunes or if there was another solution. Thanks in advance
