Error sending confirmation emails in FireFox Sync
When you configure Firefox Sync on a computer error: "The confirmation email that we sent to *****@list.ru it was returned, so we disabled the account to protect your data Firefox."
The email address is valid.
When adding additional email addresses with another device, an error occurs (address *****@gmail.com): "Failed to send email".
Now on one device sync works and the other not.
Please unlock the account and resolve the issue with the registration of the computer in "Firefox Sync".
