I've made a mess of the Firefox account for my personal e-mail address: I enabled 2FA through Google Authenticator and lost the details. Now I can't log in to that Firefox account and it's a real pain because this has been my e-mail address for many, many years. I know I don't have any important information in the account, and so I'd just like to nuke it and start again. Unfortunately none of the documentation I've found refers to force deleting accounts: all I can see is that removing the 2FA is not supported (e.g. https://support.mozilla.org/en-US/kb/what-if-im-locked-out-two-step-authentication). Is there a Mozilla support function I can contact to delete my account? Thanks!
