That experimental Firefox tool removes identifying data used by fingerprinters. Some browsers, such as Edge and Safari, block known fingerprinters based on blacklists, and Firefox is working on a behavioral blocking system that alerts you if a site tries to perform actions that look like fingerprinting-for example, trying to extract your hardware specs using the HTML Canvas feature. This mode usually just hides your activities from the local machine’s history. How Can You Prevent Web Tracking?Ī browser can take measures to protect you against these privacy infringements, but note that private browsing mode-variously called Incognito mode, InPrivate, or simply Private mode-usually doesn’t protect you against tracking.

A more recent threat is fingerprinting, a way of using webpage headers and JavaScript to build a profile of you based on your system configuration.
