## How to make new folders in Thunderbird default to unthreaded ## Due to popular demand (and as the pref is pretty hard to find and use), I've created a new section titled [Changing default threading mode](https://support.mozilla.org/en-US/kb/message-threading-thunderbird#w_changing-default-threading-mode) in the [Message threading in Thunderbird](https://support.mozilla.org/en-US/kb/message-threading-thunderbird) article. Note that changing the hidden pref **`mailnews.default_view_flags`** to 0 (unthreaded) will only apply for _new_ folders created after the change. For existing folders, there are other methods documented in the article. > Plus how is a non-dev user supposed to figure that out I wonder? As of today, they can find information in the support article, but I'm still in favor of exposing this pref in the settings UI.
