problem with old firefox account with an email that no longer exist
First of all sorry if my English is not correct. I have a problem trying to login to an old firefox account, though I remember the password I cannot change or add a new email because the primary email from the old account is from a email service that no longer exist (openmailbox.org), so I cannot receive the security code. Although I have a new firefox account with other mail that I use regularly, I need to access to my old account to recover an old login. Is there something that can be done or I lost my old data forever?
