The college philosophy class you barely remember aside, what the sandbox does is hides your files, your real IP address and your MAC address from the browser. Therefore, "the amount of information Tor Browser will learn about your computer, and thereby you, will be limited," Angel said.

At the time of that interview last October, the sandbox was still unstable and very much in testing, but the recent update has brought the digital safe-zone online for Linux and macOS, and by default. Next up? Sandbox protection for Windows users.

The update also imposes a few new requirements for users on Windows and macOS: Tor apparently won't work on non-SSE2-capable Windows hardware and you need to be running OSX 10.9 or higher on Apple machines.

Considering that last year a federal judge said that the FBI no longer needs warrants to hack a computer connected to the internet, this is an important update. "Even an internet user who employs the Tor network in an attempt to mask his or her IP address lacks a reasonable expectation of privacy in his or her IP address," judge Henry Coke Morgan, Jr commented at the time.
