The internet is not a private place. Every time you connect to a website, ads and beacons attempt to follow your every move, building a profile that other trackers can use to identify you. Modern browsers have privacy protections built in, but they’re not foolproof.
Cover Your Tracks is a project created by the Electronic Frontier Foundation (EFF) that aims to educate users on their browser’s uniqueness and effectiveness against tracker blockers. The site loads fake trackers and measures which ones are blocked. It also compares your browser fingerprint with its database of recently scanned browsers, generating a uniqueness score.
A recent test using Cover Your Tracks revealed surprising results: even with strong privacy settings, my Safari browser scored low in fingerprinting protection, while my Firefox browser fared better. The EFF recommends using Tor for browsing, hardcore privacy extensions like Privacy Badger and Disconnect, or NoScript for Firefox, as the simplest way to attack fingerprinting.
However, using these measures may require sacrificing some online freedom. By cranking up settings to “Safest” mode, I broke a website, highlighting the trade-off between anonymity and usability. The good news is that with the right precautions, you can significantly enhance your online anonymity.
