Forum zhromadźenstwa Thunderbird

In Thunderbird, when reading an eMail, if the Junk or Delete button is clicked on, that eMail gets marked as Junk or Deleted. For either of those selections, the next message immediately gets automatically opened without someone clicking for that to happen.

Our Suggestion is to change the Junk and Delete button features so that only marking an eMail as Junk and deleting it happens, without automatically opening the next eMail. Also, when deleting an open eMail, change it so that deleting it is all that happens, without automatically opening the next eMail after deleting one.

First I am very frustrated that someone decided to change the default to show all messages in threads. How do I globally disable this for every profile on my system. Additionally how do I disable it in one pass for all top level folders at the moment I have to change one top level folder at a time on every system I use thunderbird on, as I have over 100 folders this is very inconvenient. How do I modify a new thunderbird installation so all users and profiles default to threads being turned off.
