Today Thunderbird has been updated to the 115.2.2 version and now I have a problem with marking a few folders. Do you know how it can be done? For example I have a few folders and after refreshing mailbox many new messages have come to these folders. I would like to mark them all as read as fast as possible. Earlier I used to do it by marking folders with unread messages and choose option to mark messages as read, but now I can't do that. Can you help with this problem?
