Tor Browser review

Tor Browser offers the strongest anonymity here because it does not just block trackers, it hides where you are going. Traffic is relayed and encrypted three times across thousands of volunteer-run Tor relays, so someone monitoring your connection can only see that you are using Tor. Each website is isolated so third-party trackers and ads cannot follow you, cookies and history clear when you finish, and the browser aims to make all users look the same to defeat fingerprinting. It also reaches sites your home network blocks, which is why it is used for censorship circumvention, and it opens .onion services. The Tor Project is a 501(c)(3) US nonprofit, and the browser is free, with the project noting 6,490 donors a year. It runs on desktop and Android. The trade-off is speed, since every page travels through three relays, and there is no iOS version from the Tor Project.
