Rated 5 out of 5 stars

I found this on recommendation in a German security newsletter...

This is definitely what TB prevents from being really business-aware in S/MIME manners.

A pitty that it has not been fixed after submitting of the bug - but thanks for this Add-On!

IMHO, there's no reason to keep this in Sandbox, as many users avoid installing security Add-Ons from the Sandbox...

This review is for a previous version of the add-on (0.1.1).
