Rated 3 out of 5 stars

Worked great with TB Portable version 45. Will not work with version 52. No error messages but nothing happens when click 'send' mail. Pity, needs update.

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

I apologize that there is an issue on sending procedure at Confirm-Address 1.2.9 on Thunderbird 52. The issue has been fixed and already sent to Mozilla Foundation a few days ago, it is currently waiting for Mozilla's review. Would like you to wait until the review is done, or download Confirm-Address 1.2.9a from our support site.
