Hi Mark, First : this is a public forum and anyone can see your email address - to avoid getting 'spammed', you may want to remove it ..... Sorry to hear about your problem : '''You have received a message that your account has been locked''' First wait 24 hours until trying again. If it fails again and you still have access to the email account, then please create a bugzilla.mozilla.org account and use [https://mzl.la/2E0m0XD this link] to create a request. This is when your account is locked and you do not have access to the email account you created this Firefox account in, or the email is no longer accessible. I would recommend making a [[Back up and restore information in Firefox profiles|backup]] of your local profile first and then creating a new Firefox account. '''If there is still a problem''', please feel free to reply to this thread and we can help you the best that we can.
