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.
[For Thunderbird 52 users]
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 and has been waiting for Mozilla's review. Would like to wait until the review is done, or download Confirm-Address 1.2.9a from support site.
[How to Install]
- Download addon file (extension = xpi) from this site or support site.
- Click "Thunderbird menubar > Tools > Addon" to open addon page.
- Drag & drop downloaded addon file to addon page.
