Cannot log in to Mozilla Support. It won't accept my username or password. Reset password email says my account is already activated.

Question

Tried accessing Mozilla Support Forums for Firefox Desktop Support, which I have used many times. It would not accept my username and password, claiming they were incorrect. I tried the Password Reset feature, which opened a window saying that accounts created before December 2010 may have issues logging in. Please reset your password below. It instructs me to enter my email address so that it can send me instructions for setting a new password. I enter my email address. It says we've sent an email to any account using this address. Please follow the link in the email to reset your password. I go to my email. Nothing is there. I wait, but still nothing.
I go back to the sign in page, and click on the link - I didn't get a confirmation email - under Login Problems. A new window opens which tells me that to activate my account I must first confirm my email address. I reenter my email address. I get an email from Mozilla right away, telling me that my account is already activated, and it gives me a link to log in. I click on that link. I enter my username and password again. Same error message denying me access and telling me to enter a correct username and password. I try this a couple more times with no success. Same repeating errors.
So I try to create a NEW account using a different username with my email address. It will not let me do that. It says that email address is already taken, and it will not allow me to proceed. I ultimately had to set up a new account with an email address that I never use, just so I could access the Help features. I am exasperated. I do not want to post my Questions using an email address that I do not use, and have to open another application to even access. I want to be able to receive a message from Mozilla in my normal everyday email address, if someone has replied to my post. But since Mozilla will not let me use my existing email address for the new account I set up, I cannot do that.
This is very frustrating. Mozilla will not allow me access to my original user account that was already set up with my preferred email address. And Mozilla won't let me create a new user account with my preferred email address. Now I am stuck with a new user account that is linked to an email address that I never use and which is not easily accessible to me. As a last resort, I access my new user account in hopes that it will allow me to change the email address that is linked to the account, but of course, that is not an option.
Can someone please help me to access my original account with my original username and password? If a password reset is necessary, then I should not be getting a reply email telling me my account is already activated (see below). If it is activated, then why can't I log in? What is going on? Please help me. Thank you.
It seems your account has already been activated.

Answer 1

I use only support.mozilla.org and never used any other websites. However, the same problem here. My ID and Password are not accepted. Had to create a new account with a temporary email to use Support - it would not allow me to use my main email, because "it is used by another account". Try to reset password - receive no email (even though there is a confirmation on the website that email to reset password has been sent). At the same time can easily receive a confirmation about User ID and account activation. Thus, the account is completely locked, and I can not use my email address for a new one. Please fix this problem.
