Say's it's not compatible with the new version. Would be nice if there is a uniformed update on all. Ervery time there is an update, half of my add-ons are not working anymore.
This review is for a previous version of the add-on (0.17).So you should rather give a bad review to Thunderbird itself than on the addon?
