Mozilla today announced that its Enhanced Tracking Protection feature for Firefox, which launched in July (and became the default in September), has now blocked a total of over 450 billion third-party tracking requests from the thousands of companies that try to track you as you browse the web. That’s a big number, but with today’s launch of Firefox 70, Mozilla is also giving you a personalized dashboard that tells you how often Firefox blocked third-party cookies, social media trackers, fingerprinting tools and cryptominers.

Privacy protection is on by default, in the ‘standard’ setting, so you don’t have to do anything special to protect yourself. If you want to tinker with the settings, though, and don’t mind it if the occasional site breaks, you can also opt for a stricter default and custom settings.
