Rated 5 out of 5 stars

A nice enhancement to firefox; It both mitigates cross-site attacks and blocks web annoyances like ads and trackers. Probably best for more net-savvy denizens, since it breaks most sites, and requires a bit of intuition to know what domains to enable and how to enable them for maximum ease of use.

This review is for a previous version of the add-on (0.5.27.1-signed.1-signed).
