Enhanced Tracking Protection in Firefox for desktop

Enhanced Tracking Protection is a collection of Firefox features that protect your privacy while you browse. It blocks many of the trackers that follow you around online to collect information about your browsing habits and interests. It also includes protections against harmful scripts, such as malware that drains your battery.

Though these are invisible protections, you can see what’s being blocked on individual pages by clicking the shield shield detected 70 to the left of the address bar.
