Rated 5 out of 5 stars

The cleanest, most modern, most beautiful theme out there. If Frank Lloyd Wright designed a FF theme, it would look like this! BTW - if you're told that Rein is incompatible after you update Firefox, just go to the Rein web site and download from there: this usually works (it did today with FF 18).

This review is for a previous version of the add-on (5.2.1).
