Rated 4 out of 5 stars

Great Add-on! I wish it would work better with Thunderbird. When it locks Thunderbird 3.1.9, there is no way to unlock it. When you enter the password, it just asks it again. The only way to solve this is to restart Thunderbird.

The automatic lock and logout countdowns don't seem to be working quite right either.

With Firefox 4, everything works great.

This review is for a previous version of the add-on (1.15.1.1-signed).
