Thunderbird's faulty handling of threads

I am using Thunderbird v. 115.5.1 (64-bit) on Windows 10.

In this version, they got the crazy idea that the dialog should be displayed in threads.

The crazy thing is that when the thread is folded, you can't see now that there are new replies to this thread unless you unfold it.

I check "Not in threads" under the menu item "View" and "Sorted by". But for some reason, a serious bug I think, this notch is automatically changed back to "In Threads".

I am NOT interested in seeing my dialogue in threads as you can overlook new replies because you cannot see the marked subject line in a collapsed thread.

How do I make Thunderbird stop showing in threads, permanently?

Ok, I agree it wasn't a good idea, but there it is. To avoid it, here's the full info:


This is the official (to my knowledge) documentation. Well worth the read https://support.mozilla.org/en-US/kb/message-threading-thunderbird

Here is my own documentation on threading, duplicating the above, but it may help: You need to highlight each folder and click View>sort by>unthreaded. If this applies to just a few folders, just repeat the process as necessary. If you have many folders or plan to add many new folders, you may wish a different approach, below:

More info: To change default for *new* folders, In config editor, you can change default that applies to NEW folders you set up: mailnews.default_view_flags 0=unthreaded

Config editor is available at Tools>settings>general and scroll to bottom right.

 ------------

To set many *existing* folders, follow these steps: (I creates a crude video that walks through the steps at

   https://davidkirk.org/SettingDefaultFolderView.mp4  that demonstrates the following steps:
   First, highlight a folder that you have set to unthreaded	
   In the Message List view, in the column header, on the far right, open the options button that shows    
    context menu. :
   At the very bottom is the option:
   -> "Apply current view to..."
   -> "Folder and its children..."
   -> Hover over an account
   -> In the next menu don't select a folder. Instead select the account name itself.

Hello David

Thanks for the quick reply.

Haven't tried it yet but expect it to work so I'll close the case.

Many greetings Finn

You're very welcome. That decision they made for threading is a curse.
