I also found out, that in the latest beta version no accounts will be shown pressing the button reply and forward although these fields are marked in the settings of IC.

Identity Chooser 2 currently does not enhance the reply/forward buttons in the main toolbar. Only in the message header.

Identity Chooser 2.0 doesn't remember the settings, means, the different accounts are not shown when pressing the new message button. After deactivating and reactivating IC it works until the next start of Thunderbird 78.5.0 EDIT: I also found out, that in the latest beta version no accounts will be shown pressing the button reply and forward although these fields are marked in the setting of IC.

This is a bug that I've been working on. Please install the latest test version available from https://github.com/speedball2001/identitychooser-mx/releases. It should fix this. If you still experience the bug let me know via Github's issues.
