If it worked well in 1.5, it will also work in 1.6 if you uncheck the option "Delay password prompt until extensions are loaded" in the add-on preferences.
(There is some trade-off to take here. If I show the password prompt earlier during the startup sequence, it eliminates duplicate prompts more effectively for some users, but it also breaks some themes/translations/extensions for others. Since the latter issue seemed to affect more people, I've decided to make the old behaviour the default and offered the 1.5 one as a preference.)

Indispensable, and I've used it for years, but it no longer starts early enough to prevent multiple password prompts.This review is for a previous version of the add-on (1.3.1-signed).
