Works exactly how you would like it... it prevents sending e-mails to a lot of people using TO or CC instead of BCC.

It prevents making a stupid mistake when your used to sending a lot of mailings with Thunderbird.

This is a great app for this single goal.

This review is for a previous version of the add-on (2.1.0).
