Hello, as you probably heard, Google has been having some outage issues. Unfortunately, it was bouncing incoming messages with the code indicating that your address does not exist, which can trigger a 24-hour lock on your Firefox Account. Google said it solved these issues about 6 and half hours ago now, so hopefully you will be able to unlock tomorrow. So far, I have not learned of any way to speed it up. If you can't wait, you could file a bug report as described in this article: https://support.mozilla.org/en-US/kb/im-having-problems-confirming-my-firefox-account#w_your-firefox-account-has-been-locked
