When I click on a folder in an email account, in the upper left of the message pane, it shows how many messages are in that folder. When I open a message in a new tab, there is no indication of the number of messages, much less the number of unread messages, like it was in the previous version. The "counter" was in the lower right of the pane/tab where the progress/loading bar is. Wish it was back.

Thunderbird 115, incoming emails routed to sub-folders not showing as "new email" in the main folder. When a new email is routed to a subfolder and the folder (parent) is collapsed, the parent folder shows no indication there are unread (new) messages in one of the subfolders. When I open and close the folder the number of messages unread in the subfolder(s) pops up and indicates there are unread messages somewhere inside. Every time I use Thunderbird and walk away for a while I have to open/close all my main folders to see if there are any new messages whithin....

The "Quick Filer Bar" is now where the total number of messages in a folder is displayed. I had to go to View > Toolbars > Quick Filter Bar.

i just did what you suggested and I don't see "total number of messages" displayed. Please advise.

View > Folders > Folder Pane Header
This will make a bar with the total count, and also a button to activate Quick Filter.

I have the same problem as Cubsfan. I cannot find the total number of messages in a folder. Lots of the online instructions on this are do not work, or contain shorthand that non-developers cannot follow. This is an important feature that disappeared, and could drive me to another email reader. As a more general comment, repeated changes to Thunderbirds very complicated user interface are confusing, and seem to serve no useful purpose.

Just reinstalled Thunderbird (139.0.2) on my Windows 11 Laptop was trying to sort this. After launching Thunderbird go the the Mail tab and to the right of + New Message you'll see three dots ....Thunderbird Mail Menu
Selecting the dots will open a sub-menu with an option to Show Total Message Count enabling this feature will display the message count for each folder.

This displays the message count for ALL folders and makes is necessary to size the left folder pane wider. That is not my preference! I only want to see the count for the currently selected folder like it has been in the past.

Yes, I found it by View > Layout > Message List Header. And I agree with some of the comments that Message List Header has too much wasted white space. What about putting that count in the Quick Filter bar? The Quick filter toggle that is in the message header has the option of being placed in the Mail Toolbar.

I have explored those options. I was just musing about how one might better utilize the white space on the Message List Header. Thank you for your help and suggestions.
