Find How Many Trackers and Cross-Site Cookies Firefox Has Blocked

Mozilla Firefox is a web browser that focuses on the security and the privacy of the end users. This is why you will find a whole set of features that enhance the security of the browser. Some of these features provide protections against cross-site cookies, social media trackers, cryptominers and fingerprinters.

Cross-site cookies are used to track users across multiple websites. Usually set by a tracking site, these cookies can collect information about what you do online. Social media trackers are scripts from social networking sites like Twitter and Facebook that might track your online activities – what you do, what you see, what you watch online, which games do you play, what you download and so on.

Fingerprinting refers to the unique identification of a user through the web browser version, browser settings, screen size and various other settings. Cryptominers are unwanted scripts embedded on a webpage that use your computer’s processing power to mine digital currencies or coins like Bitcoin. Cryptominers can make your system slow, drain your battery, make your system’s temperature rise and increase your power bills.

Firefox provides protections against all of these by default. You can visit about:preferences#privacy in Firefox to see that you have selected all the protections and they are all enabled. After you have used Firefox browser for a while, you can find out how many trackers, cross-site cookies, cryptominers and fingerprinting attempts it has blocked.
