I have forgot my password to my account and also lost the 2FA codes. '''Since I have no longer access my account, I want Firefox to delete my account.''' I used a backup email on that account. I tried to open a new Firefox account with that backup account, but I wasn't allowed to create a new account with that backup email address. I can provide you my national ID,passport and other ID cards to prove that '''I am the real owner of the account'''. You can even video call me if you want but please delete my account so that I can open a new account with those emails.
