Tor Browser is a fork of Firefox designed for anonymous browsing for desktop computers and Android. It’s our top choice if you need anonymity, as it provides you with access to the Tor network and bridges, and it includes default settings and extensions that are automatically configured by the default security levels: Standard, Safer and Safest.
You should never install any additional extensions on Tor Browser or edit about:config settings, including the ones we suggest for Firefox. Browser extensions and non-standard settings make you stand out from others on the Tor network, thus making your browser easier to fingerprint.
The Tor Browser is designed to prevent fingerprinting, or identifying you based on your browser configuration. Therefore, it is imperative that you do not modify the browser beyond the default security levels.

Tor works by routing your internet traffic through those volunteer-operated servers, instead of making a direct connection to the site you’re trying to visit. This obfuscates where the traffic is coming from, and no server in the connection path is able to see the full path of where the traffic is coming from and going to, meaning even the servers you are using to connect cannot break your anonymity.
As of April 2023, Tor Browser is not yet available on iOS. You can use Orbot to connect to the Tor network with another browser on iOS or Android, but this does not provide the strong anti-fingerprinting protections Tor Browser would normally provide.
