Usually great add on - is it working with 78.0?

This review is for a previous version of the add-on (1.9.9). 

Hi,

thank you for your interest in a version of Identity Chooser for Thunderbird 78. You can download a beta version from https://github.com/speedball2001/identitychooser-mx/releases/tag/2.0beta1
