Rated 5 out of 5 stars

The latest enhancement works with Thunderbird 52.
Thank you, thank you, thank you!

This review is for a previous version of the add-on (1.2.9). 

Would like you to recommend it to your friends, colleagues.

It is with great appreciation, I announce that Confirm-Address 1.3.0 which supports Thunderbird 60.* is now available. I thank all the Confirm-Address users for your patience.

Wonderful add-on. Let us know how we can upload the latest version compatible with Thunderbird 52. I couldn't see a "support site." Thank you!
