Rated 5 out of 5 stars

Nice extension to have an accessibility friendly behavior in Thunderbird.
i cannot set the focus as I wish but it is thanks to Debian Buster which has not enough recent version of Thunderbird.
Thanks a lot!

This review is for a previous version of the add-on (2.3.0). 

Dear Patrick,
Which Thunberdird version and which Add-on version do you use?
If you use the Add-on version 2.3.0, in the Options you can choose if the focus should be set on the folder or on the last message.
If you have any problems, please contact me via k-l-p@gmx.de.
Best Regards
C-E
