Hi, sorry having a issue. If you were not did not know using all caps is considered shouting on the internet. I will give you what I have on Sync : *https://support.mozilla.org/en-US/kb/how-do-i-set-sync-my-computer *https://support.mozilla.org/en-US/products/firefox/sync *https://support.mozilla.org/en-US/kb/how-do-i-choose-what-types-information-sync-firefox *https://support.mozilla.org/en-US/kb/firefox-sync-troubleshooting-and-tips *https://support.mozilla.org/en-US/kb/change-primary-email-address-firefox-accounts Please note that Firefox Support has no access to anything to do with Sync. Or contact with data or login/accounts. In the below URL at the bottom is Contact for bugzilla. Please use that contact as it directs to make a account and describe the issue you are having. Then wait. There is contact info in this and yes do have to create a account and wait : https://support.mozilla.org/en-US/kb/forum-response-firefox-sync-verification-email-faq Again sorry having problems but bugzilla will help you. Please let us know if this solved your issue or if need further assistance.

This sometimes happens if you accidentally type the wrong year for your year of birth. I don't know if your email address is now permanently blocked or whether it will clear up over time. Note that you do not need a Firefox Account to browse websites. This article describes some of the optional services it would be useful for: [[Access Mozilla Services with Firefox Accounts]].
