About this Add-on
Once you register YOUR DOMAIN (ex."mycompany.com"), you will see Confirm-Address dialog with highlighted mail addresses when you send mail to other domain. And so, you can raise awareness of security and information leak.

It is with great appreciation, I announce that Confirm-Address 1.3.6 which supports Thunderbird 78.* is now available. Since it supported MailExtension, user interface is totally renewed. None of its feature doesn't change/improve.
[Nov. 11, 2019 For Thunderbird 68 users]
It is with great appreciation, I announce that Confirm-Address 1.3.5 which supports Thunderbird 68.* is now available. Since it also supported WebExtension, users who want to keep Thunderbird WebExtension-free, please download version 1.3.3 from support site. Also, Confirm-Address 1.3.5 fixed a bug not sending mail when a preference mail.warn_on_send_accel_key was not defined. I thank all the Confirm-Address users for your patience.
