Facebook offers a link to download an ical file of friend's birthdays. It looks like this... webcal://www.facebook.com/ical/b.php?uid=12345678&key=98765432 When I click on the link Firefox says "Firefox doesn't know how to open this address, because the protocol (webcal) isn't associated with any program." I went into Tools/Options/Applications but there is no way to add an app to tell it to download. Any thoughts?
