I recently updated my old email address in Firefox Accounts by filling a secondary email with my new address, making it primary email and deleting the old one that became secondary email. Now, I keep receiving tips & stuff from Firefox Account to my old email address. It is impossible to unsubscribe because my account is no longer linked to my old email address, so I can't log in. Actually, if I try to log in with my old email address, it says that "primary email address is needed to log in", proving it recognizes my old address as a secondary email, even though it no longer appears anywhere on my profile. What do?
