From the developer:
Defend yourself against tracking and surveillance. Circumvent censorship.
Tor Browser isolates each website you visit so third-party trackers and ads can't follow you. Any cookies automatically clear when you're done browsing. So will your browsing history.
Defend Against Surveillance
Tor Browser prevents someone watching your connection from knowing what websites you visit.
