Mozilla is bringing a couple of new privacy- and security-focused features to Firefox today, kicking off with the of the browser.
So-called “” has emerged as a popular mechanism for tracking web users as they move across the internet inside a browser. It works independently of cookies, and allows companies (including advertisers) to build a picture of an individual over time through tracking a mixture of signals from their machine’s configuration, such as time zone, screen resolution, HTTP headers, and more.
While cookies are fairly easy to spot and block, fingerprinting is much harder to detect. Fingerprinting also happens to be against Mozilla’s recently anti-tracking policy, which is why it is working with Disconnect to compile a list of known domains that serve fingerprinting scripts.
