I changed my email address for Sync a while ago. Now Firefox asks me to Reconnect to Sync, but my old email address is unkown, and my new email address isn't Primary, and to login / connect, that's what I need: my Primary address. As far as I remember, there's only one e-mail address in my Firefox account. If there are more, it's the old and the new one... Please advise? EDIT: And now it works again without problems... Never mind...
