What is an anti-fingerprint browser and what does it do?

Over the past few years, browser makers have realized that website tracking of users will turn to browser fingerprinting.

Firefox was the first to address this issue by adding an anti-fingerprint setting to its browser that allows users to block attempts to fingerprint their browser. A few months later, Apple began to follow suit, deploying a different method to have Safari return the same value for certain fingerprint data points, such as fonts.

The unfortunate truth is that none of these methods from all browser manufacturers are effective at preventing websites from fingerprinting users.

What is user fingerprinting?

For non-technical users or readers unfamiliar with the term, a user fingerprint is a collection of technical details about a user and their browser. They include large amounts of data such as platform details and Web API measurements.

Platform details include data points such as operating system details, browser type and version, hardware equipment specifications, a list of installed fonts, details about size and resolution, and more.

Web API measurements include the results of scripts that advertisers or analytics companies run covertly on users' browsers. For example, they can measure how the browser draws through the canvas, WebGL renders various elements, how fast the browser generates sound through the audio API, and more. All of these API operations, while identical, are rendered slightly differently depending on the capabilities of each user's browser and hardware platform.

User "fingerprints" are the result of combining user platform details and Web API measurements. The more data points an advertiser has, the more accurate the fingerprint can be and the better it can track a user's activity on the web.

In order to prevent websites from obtaining our real fingerprints, only professional anti-fingerprint browsers can do it.
