### Steps 1. In the messages listing pane, activate "Display message threads" 2. Activate "Sort by read" ### Expected All unread messages appear at the top of the list, including threads with unread first or subsequent messages. ### Actual All unread messages, which are not part of a thread as well as threads with the first message marked unread appear at the top of the list, sorted also by date with the newest first. Then unread messages and threads follow, newest first. Threads with subsequent unread messages are sorted as part of the "unread messages", therefore hard to find / easy to loose track off. I don't think exactly this has been raised yet here: https://bugzilla.mozilla.org/buglist.cgi?quicksearch=thread%20order%20by%20read&list_id=15804071

Then read messages and threads follow, newest first. Threads with any subsequent messages being marked unread are still sorted as part of the "read messages" list, therefore harder to find / easy to loose track off. --- I don't think exactly this has been raised yet here: https://bugzilla.mozilla.org/buglist.cgi?quicksearch=thread%20order%20by%20read&list_id=15804071
