With the release of Firefox 57 (Firefox Quantum) in November 2017, Mozilla added an option to enable Tracking Protection outside of private browsing. The feature’s blocking list, which is based on the tracking protection rules laid out by the anti-tracking startup Disconnect, is published under the General Public License and available on GitHub. It blocks website elements (ads, analytics trackers, and social share buttons) that can track you while you’re surfing the web. Mozilla added Tracking Protection to Firefox 42’s private browsing mode in November 2015. To explain this feature correctly, we must look at its predecessor. Windows, Mac, and Linuxįirefox 63 for desktop brings support for Enhanced Tracking Protection. In other words, it’s a major platform that web developers must consider. According to Mozilla, Firefox has about 300 million active users.
