Use cases :

- hide your real IP address.

- hide the domains that you are visiting.

- hide the information between you and those sites.

- avoid trackers and ads.

- avoid inopportune or dangerous scripts.

- bypass censorship policies.

- download things.

Advantages :

- nothing to install

- available everywhere from any modern browser

- https used even to access sites not supporting it (then extending HTTPS Everywhere concept)

- destination hidden even during the https handshake

- no third party software

- relies on the fact that you only trust yourself - even potential malicious components inside the browser could not compromise you

- very difficult or impossible to block since the js code and the pac file can be distributed everywhere and you only need this to run the js OP

Techno :

Javascript implementation of the Tor (or Tor like) protocol (Onion Proxy and Onion Router) which anonymizes communications via the Tor (or Tor like) network. This allows to simply connect to the Tor (or Tor like) network and use it, as well as creating and adding nodes into the network, creating complementary and/or parallel networks, implementing completely, partially or not the Tor protocol or a derived one, using completely, partially or not the Tor network, it can be used to create separated Tor like networks.

But the most challenging goals are to put the OP and the OR inside the browsers.

It's done for the OP : 9th February 2013's first successfull complete communication from the browser with the js OP totally inside the browser.
