Hi
I'm very happy with CB extension. Thanks !
Recently, 3 additional column added by CB appear in the message list panel (Sender (CB), etc.). This is the default view and it always come back. How can we permanently modify this default configuration ?

In response to your comment, the 3 columns come back every time Thunderbird is updated. In all the folders !

This review is for a previous version of the add-on (100.0). 

I can't reproduce : the deletion of them is correctly registered by Thunderbird
