Mozilla has announced that it will block fingerprinters by default in Firefox 72 as part of its Enhanced Tracking Protection feature.
Unlike tracking cookies which require users to opt in, fingerprinters are a tracking method that allow companies to track you without your consent based on the characteristics of your computer.
They work by building a profile of your device based on a number of characteristics including your screen resolution, which browser you use, timezone, language, the extensions and fonts you’ve installed and your operating system.
