I have a Mozilla logon for an obsolete email address with a now unacceptably short password. How can I change both address and password?

more options

I cannot logon to Mozilla Add-ons even using the old email address: it tells me that my old password is now too short and must first be reset. But the registered email address (and ISP) no longer exist to which password-reset authorisation would be set. Therefore I certainly cannot change either the email address or the password.

I have created a new account, which is what I am using to ask this question; but I cannot use my preferred user-name as "it is already in use". How can I delete the old account to be able to start again from scratch?

Just a correction to the question:

I am posting this question via my Mozilla Support/Forum account. The account I cannot open or change is what I want to use for creating add-ons for Firefox and/or Thunderbird

Sorry for the confusing account situation, but I believe Add-ons and Support accounts are still separate.

The Contact page for the Add-ons site doesn't seem to address login issues: https://developer.mozilla.org/Add-ons/AMO/Policy/Contact

Maybe ask on their forums? I guess you would need a new account for that... https://forums.mozilla.org/viewforum.php?f=20
