I have tried 4-5 times today unsuccessfully to setup my Firefox browser on my new Mac laptop. Cannot seem to actually receive any emails from Firefox with the verification codes. Have checked my spam filters, no emails sent there. Nothing sent to other email folders. Made sure accounts@firefox is in my address book. Not forwarded to another email address. And have sent test emails to my account associated with my Firefox account. They come thru successfully. But nothing at all from Firefox. Is there an email problem today from the Firefox servers?
