I tried to log in to Firefox forum, but had forgotten my password. To correct this, I tried to get my password reset via email, but found that I had forgotten my username, which I originally had to modify because my name was in use. My email address was not enough, they wanted the username too, so my application was not accepted. I tried registering, which confirmed that my email address was already in use. Dead end. What a silly problem. Is there any solution other than getting a new email address?
