Update happened late at night... either the night of 8-20-24 or 8-21-24. I believe is was a Thunderbird update because the next time I opened Thunderbird, it opened multiple windows, one of which was a "donation" window. I minimized that window, went to check my email and only one of about 7 email addresses were still there. The one that was left was a @verizon.net address. All @gmail.com, @frontier.com, @yahoo.com, and one @verizon.net addresses were deleted along with every saved email at those addresses. [place sad emoji here]

Would be great if I could get a reply on this issue.
