When you have threading enabled, new messages are placed into their thread and this may not be at the top of the screen. I suspect that Thunderbird is using the first message as the sort criteria for thread order. However, it would be more useful if it used the _newest_ message in a thread. That way, when a new message gets put into a thread, the thread is elevated and everything new appears at the top. Mutt has this feature and is enabled by: set sort=threads set sort_aux=reverse-last-date-received Reproducible: Always Steps to Reproduce: Expected Results: Threads with the newest message should appear on top.

This happens, except: as new messages arrive, the threads are not reordered. If that reordering is the behavior you want, please mark this as a duplicate of bug 262319. Otherwise, this bug should be marked as Invalid. btw, multiple sort criteria is bug 57898.
