Amazing

it just works.

It is a very good and dynamic app when it comes to your privacy while surfing the world wide web.

Super great extension for blocking trackers, and ad-blocking!

Have been using it for years, and is a great addition to the Mozilla web browser.

Incredibly effective. Very reliable. Works alongside other extensions with similar or overlapping functions. It's a must have in all my browser installs!

Works like a charm, keep it up!

great blocker for ads and other things DOWNLOAD IT the best (:

Having tried many ad-blockers Ghostery has proven itself to be amongst the very best and is now my default choice. Do yourself a favour and install it.
