My dev account at Mozilla has been hacked and my addons deleted.
My email has been changed there as well so I cannot do a password reset.
Please advise as to who and how do I fix this?
The only people who can help you are the addons.mozilla.org sysadmins. The quickest way to contact them is IRC: irc.mozilla.org, channel #amo.
This is not really on topic for SO.
