Change the #default sorting order in #Thunderbird - Super User
Is there any way to globally change the default sorting order to “Threads, newest messages at the top” (or anything else, which, I assume might be possible as well then)?
So if you wanted to sort all mail by #Thread, Descending (newest at top), the preferences in the config editor will look like this:
mailnews.default_sort_order: default integer 2
mailnews.default_sort_type: default integer 22
