I walked through all of my folders, and for each I clicked on 'Properties' and then checked the box that says 'When getting new messages for this account, always check this folder'. This is an absolute show-stopper for me - if I am missing emails because Thunderbird isn't showing me that they exist, I will be forced to migrate to a different email client. Should see an unread count for all folders to which I am subscribed (if they contain new unread mail) without having to visit the folder. Not seeing new (unread) mail count in other folders until I visit that folder. Recently I do not see any unread count in other folders until I manually click on the folder name to move into that folder.
Until recently Thunderbird would show unread mail counts in other folders (after I did much configuration of things like mail.check_all_imap_folders_for_new=true and _all_folders_for_new=true and _status_for_biff=true as suggested by ).
I have it autofilter mail to many different folders. User Agent: Mozilla/5.0 (Windows NT 6.1 WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/.103 Safari/537.36
