Rated 5 out of 5 stars

OMG!!! This is EXACTLY what I was looking for... Everyone on the forums was telling me that I needed to use some OS technique or other software to password protect Thunderbird, but this does it PERFECTLY - with all of the settings that you can choose. I find the exit if master password is cancel the most VITAL option for me :). Thank you! GREAT addon :)

This review is for a previous version of the add-on (1.16.1.1-signed).
