Rated 5 out of 5 stars

One of the most useful addons in means of usability and security.

At thunderbird startup the master password has to be entered only once and thunderbird won't open before entering the correct master password.

Recently a bug occured after an update and the developer provided a bugfix within some days, so everything works fine again. My acknowledgment for that fast reaction.

This review is for a previous version of the add-on (1.30).
