Locked out of my account for no reason
Bought a new M1 Mac. Was very happy when an M1 version of Firefox got released today only to find my account locked out trying to sign-in. I received the infamous message: "The confirmation email we sent to email@example.com was returned and we’ve locked your account to protect your Firefox data"
That is not true. I am receiving emails just fine and I never lost access to my email account.
Google is having issues. The Gmail outage may be rejecting messages to your account from the Firefox Account server, or the problem may be very intermittent.
I suggest waiting until we hear more from the Firefox Accounts team on whether they can do something on the back end for all Gmail users affected by lockouts.
