Hi, Mozilla has been a part of my life since the dial-up times, with Thunderbird and even some time with the Mozilla Suite (https://en.wikipedia.org/wiki/Mozilla_Application_Suite). So I had an account on the Thunderbird add-on page and created some collections and also a Firefox account for sync. Since the Firefox account became the Mozilla account, I haven't logged into the Thunderbird add-on site: https://addons.thunderbird.net Just now I noticed, that there is only the Mozilla account login available and I cannot get into my old Thunderbird account. If I log in with my Mozilla (formerly Firefox) account, I am logged into a new/empty/un-customized account on the Thunderbird add-on site. If I try to change my username to what I used before, it tells me that username is taken. That means my old account still exists! Yay! Now my question is, how do I recover it? How do I log back into it? Can I connect it to my Mozilla account? Other people seem to have run into the same issue: https://connect.mozilla.org/t5/discussions/how-to-connect-thunderbird-to-my-mozilla-account-without-loosing/td-p/56623 Please help me with that. I would love to engage on the Thunderbird add-ons page again. Have a great start to the new year Joda PS: I got sent here by the Mozilla Account support team, that I contacted through: https://support.mozilla.org/en-US/questions/new/mozilla-account/form
