Über dieses Add-on
Due to Supernova changes in Thunderbird, it is no longer possible to manipulate columns from an add-on, even with full privileges. There are proposed changes to re-enable the feature and a request to have this feature built-in. Until those changes are merged and released, the add-on can't be fixed.
This add-on adds two new columns called "Sender (@)" and "Recipient (@)" in
message list containing full, raw addresses of sender and recipient instead
of just names like in default columns.
This add-on is reimplementation of "Show address only" add-on, which stopped working
in Thunderbird 78. This add-on source is heavily inspired by "SFreq" add-on source by Jorg K.
