Crucial and the ultimate safety companion! Rated 5 out of 5 stars

Flawless functional add-on, uses pre-internet encryption, very heavy unbreakable keys stored where they need to be stored. NSA must hate these developers! Generates passwords that are *as robust as you set them to be*. They can not be any less robust than what you would make up on your own, in most cases the generated passwords will be A LOT better than what you currently use for your valuable log-ins.
Have tested this to the bone using wireshark and other tools, since it's closed source (for the most part). It ends up being the best out there. Simply unbeatable. A life-saver. Best of all: You can't lose your stuff, not even when they stop existing.

This review is for a previous version of the add-on (1.90.6).
