Rated 5 out of 5 stars
Excellent add-on for keeping those nosy analytics sites from tracking your every move on the 'Net. With a few quick, minor tweaks to the preferences (to allow the "bugs" I like), I've been using it for days with stellar success.
Install this add-on immediately if you care about your browsing privacy. Note that Ghostery doesn't protect your _data_ privacy (eg. SSL, MiTM, etc.), but does protect against most of the ways Big Brother tracks your every move.
