I'm not entirely certain if this is the case for you, but it's possible that your account was removed. A while ago, Mozilla tried moving the support site to another service. I don't believe that they transferred all of the accounts over.

However, it's also possible that they simply removed your account for inactivity.

Many thanks for the prompt reply. I think that you are correct. In the meantime I followed instructions I found somewhere here and opened a new account by posting the above query.

So, problem solved. Many thanks to all.

If you know the exact spelling of the old account name then manually put the name of end of this url. If the account exists then it will load the account profile page.

https://support.mozilla.org/en-US/user/

For example you account used to post this thread is https://support.mozilla.org/en-US/user/Cobracon9

Many thanks for URL - that also worked!

In trying to access Mozilla Forum, I can't verify either the Account Name or the password. One work around suggested was to just start a new account, but when I do that, it says that I can't because my email address is still attached to my account.

So I feel absolutely stuck in an infinite loop. Any idea of how to get out of this. My email addressed is attached to Community Support account as well.

Thanks, Mac Lingo
