This applies to the whole support forum on support.mozilla.com. I have an old account on support.mozilla.com. The username was my email address. I tried to log in with that username and the old password and it was rejected. I asked for a password reset, reset the password, got to a login page, put in the old username (email address) and new password, and it was rejected. I tried to create a new account, and it said there was already an account with that email address. I had to create a new account with an alternate email address. I tried to log into the new account with my email address as username, and it was rejected. It only takes the short username. Apparently I need a username to log in to the old account, but it doesn't have a username. Am I forever locked out of using my preferred email address for the Firefox support forum and forever destined to use a secondary email address? Or can you send me a valid username for that account?
