This addon has its "Ghostery Rewards" function turned on by default, which basically sells your information to certain companies which the developers have "whitelisted."
Ghostery blocks third party tracking and ads. Ghostery Rewards operates locally, meaning it is completely contained within your browser and does not transmit personal information back to Ghostery, Cliqz, or any other third party companies. It can be disabled in the settings menu.
