What account? Firefox browser user help forum has no access to anyone account and if your reset doesn't work or email fails then that's a lost account. Otherwise you should check your registered email to see what the reason for the lockout if there is one.

I already used support to understand why I have this message...with no reply. My account is connected to my Gmail, I have the autenticator on my mobile phone and I do get this message when I try to do anything. I thought I could get some support in here... Would you be able to indicate me the right place? Thank you in advance.
