The latest update for privacy-minded folks' favorite way to surf the web should make others' attempts at tracking what they do even more difficult. The Tor browser's 7. 0 version introduces a sandbox feature that, according to an interview on the Tor blog, should "make life a lot harder" for people using a Firefox exploit to discern the identities of a user. "It's like Plato's Allegory of the Cave," Tor developer Yawning Angel said. "The only reality Tor Browser knows is inside of the sandbox (cave). We prevent it from interacting with the rest of your computer (the outside world), except via the Tor Network (shadows on the wall)."
