I understand that you are encountering issues with signing in to your Firefox account. Please find the following scenarios that your account may be in and the next steps to take:
You are not receiving an email verification email or You are not receiving a password reset email
- Please check your spam filters or your spam folder.
- Please try to access your email from the webmail client, not your email software.
You have received an email was returned message
I would recommend checking the following at this point:
- Please check to make sure in your email settings that the accounts@firefox.com email is not flagged as spam.
- Add accounts@firefox.com to your address book. This will make it a trusted email.
- If you have tried all of the above, do not try to do this again until 24 hours have gone by, or else your account will be locked.
You have received a message that your account has been locked
This is when your account is locked and you do not have access to the email account you used to create this Firefox account, or the email is no longer accessible. I would recommend making a profile backup first and then creating a new Firefox account.
First wait at least 24 hours and then try again. If you’re still unable to log in, contact us through this link.
