All major spider web browsers include features that permit yous cake common tracking methods, simply tracking users is big business. It'southward understandable advertisers have come up with some clever ways to quietly follow you effectually the web without cookies or ad tokens. I of the well-nigh stray techniques is known as canvas fingerprinting, but it won't be a problem for Firefox users anymore. Firefox is rolling out an update that borrows from the Tor browser in gild to prevent users from being tracked beyond websites via sheet fingerprints.

Most advertizement networks employ tracking cookies of some sort to follow a specific user around the spider web. That data helps target ads and generally earns everyone more than money. Well, everyone but the user. Canvas fingerprinting tin can also exist used to runway you, but it's not based on cookies. Thus, turning on the "do not track" flag won't exercise anything to stop it.

Websites that use this method instruct a browser to draw a hidden line of text or a 3D graphic using the HTML5 canvas element.
