Stashed in: Firefox!
Ghostery™ sees the invisible web - tags, web bugs, pixels and beacons. Ghostery tracks the trackers and gives you a roll-call of the ad networks, behavioral data providers, web publishers, and other companies interested in your activity.
I wouldn't have known this was a Firefox add-on if Greg hadn't said so.
One of my favorite firefox add-ons!
And my son, as he likes the ghost!
Thanks for recommending it, Greg.
