What is the Tor Browser?

The Tor software protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, it prevents the sites you visit from learning your physical location, and it lets you access sites which are blocked.

What is ProxyChains ?

proxychains - a tool that forces any TCP connection made by any given application

to follow through proxy like TOR or any other SOCKS4, SOCKS5 or HTTPS proxy.

Supported auth-types: "user/pass" for SOCKS4/5, "basic" for HTTP.

Tor sometimes can't give you complete security. There is a chance of DNS leak. But with this method you will be able to hide yourself safely.
