Rated 3 out of 5 stars

Vielen Dank für das hilfreiche Tool. Leider nicht kompatibel mit der neuesten Thunderbird-Version. Wann erscheint endlich das Update?

This review is for a previous version of the add-on (14.0.0).

Thanks for the review.
Actually it is already released!
The addon site does not show it because of a quirk.
You can download the official release here:
https://github.com/thundernest/import-export-tools-ng/blob/master/xpi/import-export-tools-ng-14.0.0-tb.xpi

Then use Install Add-on from file on the addon tab
