Almost perfect Rated 4 out of 5 stars

Worked fine for me, except there is a bug in the stealther.js file causing the history expiration date to be set to zero days permanently.

Change browser.history_expire_days to browser.history_expire_days_min on the 2nd line of the last 'else' block of this file, and it will work fine.

This review is for a previous version of the add-on (0.99).
