Review for Force Authentication at Startup. by Anonymous
Rated 5 out of 5 stars
Many thanks for this add-on.
This one is finally working good. Every others I've tryed yet was easily by-passable by closing the password window till the main page appears.
This one never let ThunderBird open if you don't enter the correct password.
Never.
And this is a MUST.
