This plugin does not work with Thunderbird 68.1.0 Please add support. Thank you!
This review is for a previous version of the add-on (1.1). This user has a previous review of this add-on.The add-on meanwhile supports Thunderbird 68+. So you may consider updating your review.
Please report any issues on https://github.com/DDvO/Duplicate-Contacts-Manager/issues/ rather than (ab-)using the list of reviews, which I do not track regularly, for this purpose.
