Rated 5 out of 5 stars

I was looking for some points to deduct a star, but currently i can't find them. Its a really nice and usefull addon.

Just one thing: when using thunderbird, and i have set ask password at startup it looked to me like TB got hung up when it tried installing new update (just disabeled it for one start then and its fine)

This review is for a previous version of the add-on (1.15.4.1-signed).  This user has 2 previous reviews of this add-on.

Unfortunately I don't know any way make MP+ execute before anything else, therefor it's possible that MP prompt window showed after some other window already showed, which might halt everything until MP is entered.
