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. After showing you who's tracking you, Ghostery also gives you a chance to learn more about each company it identifies. How they describe themselves, a link to their privacy policies, and a sampling of pages where we've found them are just a click away.
- Ghostery is not a ad/content blocker.
- Ghostery tells you when a website is requesting private information (and offers to block the request). uBlock prevents advertisements from loading.
- Some overlap, but Ghostery is focused more on privacy and uBlock more on usability
