It still sometimes happens that the message list jumps to a different position after deleting a message. Unfortunately I don't have any STR. I can only say that I have something in my quick filter text field and that the deleted mails were neither the oldest nor the newest mails, they were somewhere in the middle. I read and delete at least 100 mails per day and most times there are no issues, it only happens a few times per day. This makes it very difficult to provide more useful information.

Thunderbird Daily 117.0a1 (2023-07-21) on macOS 13.5.

Same as bug 1843462?

Maybe there is a similar cause but I don't think it's the same. Bug 1843462 says "new messages on the bottom(this is required)" but I have new messages on the top. I don't use the context menu. And it scrolls a bit but not "all the way to the top".

Is this better on Daily now? I don't think the sort order matters for the changes I made in bug 1843462.

I tested again in Thunderbird Daily 118.0a1 (2023-08-04) and it happened two times.

Happens in the release 115.1.1 all the time for me. There are two other bugs that are marked as fixed and verified, but that's not correct, the bug still exists! Bug 1835173 and bug 1833845. When I delete a message, the list jumps so far down that everything I previously saw is now out of view. Very annoying.
