Ghostery — open-source browser extension for blocking ads and trackers.
Ghostery is a fully free, open-source tracker and ad blocker that gives users unusually granular visibility into who is tracking them on any given page. Ghostery discontinued paid tiers entirely, removed user accounts in October 2025, and dropped its standalone mobile browser to focus exclusively on free, account-free browser extensions. Funding is now entirely via voluntary community donations.
Ghostery earns its place by combining best-in-class tracker transparency with zero cost and zero account requirements. The October 2025 account removal and full open-source pivot removed the last meaningful trust concerns for privacy purists.
Default settings are intentionally conservative — users must manually enable stricter blocking to get maximum protection. YouTube and some heavily-scripted sites occasionally break. Firefox performance trails uBlock Origin on pure blocking efficiency.
