Rated 4 out of 5 stars

Excellent.

I used RoboForm, until they started charging for it. Then I was hooked on 1-Pass, but it can't work everywhere, and has form-filling problems. Then I discovered LastPass.

Wish they hadn't "upgraded" their iPhone app to become a limited-time offer, then demanding a fee for access to the otherwise-free service.
This is the best password manager I have ever used.

This review is for a previous version of the add-on (1.51.2).
