Hi Tromzy , my name is Shane Tomlinson , I ' m one of the developers on Firefox Accounts . I ' m sorry to read about your experience here , I realize it ' s frustrating . We have been trying to figure out why many emails are not being received . Sometimes delivery is slow , sometimes the email arrives in span , sometime emails just never arrive at all . As developers , we do not have access to the production logs to check if there was anything wrong with sending your particular email , unfortunately I cannot say with any certainty what happened . If you don ' t mind , would it be possible for you to PM me which email provider you use and we can see if it ' s an emailprovider wide problem or a oneoff problem ? You can follow along with some of our progress in learning more about our email delivery failures at authserverpull 1329 authserverissues 1488 authserverissues 1528
