Rated 4 out of 5 stars

This is a great add-on, and I think we should see it reviewed and taken out of the sandbox. Not just useful for Mozillians, but anyone who rotates their passwords frequently.

One nit, though: there seems to be an inefficient code loop for the reset-by-password dialog. You should probably be chunking the input instead of doing the search after each character, as the UI isn't very responsive.

This review is for a previous version of the add-on (1.03).
