I have been using this add-on comfortably for the last few years, but now that I switched to TB45.0 from ESR 38.x, the sending of e-mail does not seem to work, and thus I have to disable it for now. The rating is 4 due to this. I hope the issue can be fixed shortly now that TB 45.0 is out. Thank you for sharing this add-on.
This review is for a previous version of the add-on (1.2.8).
Thanks for using confirm-address. Until fixing the issue, please use TB 44.0b1 or TB 38.7.2 . https://ftp.mozilla.org/pub/thunderbird/releases/38.7.2/ https://ftp.mozilla.org/pub/thunderbird/releases/44.0b1/
