Hello Matt, No doubt I created most of the problem here. When I tried to signed into the Donor Portal a month or so ago, I didn't have a new email address yet, so I (apparently) used my old gmail, to which I no longer have access. i moved overseas and neglected updating gmail. In any case, I can't log in to the Donor Portal to fix this. I thought I already did get this straightened out several weeks ago, until yesterday, when my bank account showed a debit from Thunderbird. I really appreciate your help, and if you have any further ideas, please let me know. [edited email]

Jjst fill in the form at the link I provided and wait for someone to contact you.

My understanding is Mozilla have closed for Christmas and will not be returning until the 2nd of January so it might be a bit of a wait for a reply.

Most of MZLA is closed. However, the MZLA donor team is still working, so you should see a reply within a day or two of reporting your issue using https://www.thunderbird.net/en-US/donate/help/
