Unable to select account in TB 24 Rated 5 out of 5 stars

In the very last version of Thunderbird (currently in beta) the account list appears to be empty, so it is impossible to exclude accounts you don't want to be notified of.
5 stars for all the rest.

This review is for a previous version of the add-on (0.4.3).  This user has a previous review of this add-on.

Solved in version 0.4.4
