Hello, we are running Thunderbird 128.1.0osr (32-bit) released on 8/6/24. Ever since the upgrade my husband's email has not worked correctly. Around that same time, he received a pop up within the Thunderbird app asking for donations from Thunderbird. The popup would not go away and my husband lost a ton of his email. Ever since these two events his Thunderbird email won't work correctly. Messages since 8/4/24 at 6:32 am DO work correctly. Emails prior to 5/6/23 also work correctly. Any message in the time period from 5/6/23 at 11:26 am to 8/4/24 does NOT work correctly. We are having the same trouble with the sent items folder. We use a third party email that we import into Thunderbird and have used the third party email and Thunderbird since at least 2020 and never had this problem. We can see all the message headers in our email list, but when we click on the email, nothing shows up. It will briefly say "message loading" at the bottom corner, but the email is totally blank. Furthermore, the message that peeks out at the bottom is the last email that we clicked on from the section of emails that does work. It is not changing to the email we are actually clicking on. For example: lets say we have an email with message header "thank you for your order" received on 8/15. We click into that and it pulls up fine. Then we go into older email from 7/31. The message header is "hurry sale ends today". If we click on that, it will say "message loading" at the bottom corner. However, the message preview at the bottom of the screen still displays the from/to/subject from the previous email we viewed from 8/15 "thank you for your order" (the message from 8/15 shows as blank though). Even if we double click the message from 7/31 that we are trying to view, it just pulls up a blank screen. The bar at the top will briefly display the correct message title that we are trying to open, then it just blanks out. Steps we have taken: 1. In Account Settings/Privacy I clicked to "allow remote content". This made an improvement as prior to this we were having the same problem even with recent messages. We could see one or two messages that had just arrived, then the third message we couldn't see. We have messages set to delete on the server after so many days. So I think it was able to recover the message that were still on the remove 3rd party server. 2. We moved a lot of the emails into archive folders as I thought the inbox may be too large. That didn't make any improvement. Thanks for any help you can provide. My husband has a lot of really important information in his emails that he needs.
