Rated 2 out of 5 stars

be aware that the "remove all pages viewed in the closed tab from the browser's history" option doesn't work completely. many pages may still be left in the history. so don't rely on this add-on to provide reliable privacy!

This review is for a previous version of the add-on (0.8.1).
