Tracking generally refers to the collection of a person’s browsing data across multiple websites. Firefox for Android’s Enhanced Tracking Protection feature uses a list provided by Disconnect to identify and block trackers. When you use Strict Mode, the Total Cookie Protection to prevent sites from tracking your activity from site to site while allowing non-tracking cookies (cookies that are required for a website to work properly). To learn more about what third-party trackers Firefox handles, see Third-party trackers
Enhanced Tracking Protection is enabled by default. When you visit a web page with trackers, a shield icon 
will appear in the address bar to let you know that Firefox is actively blocking trackers on that page. In Strict mode, Firefox activates Total Cookie Protection which isolates cookies to the site that created them to prevent cross-site tracking. Firefox makes an exception for non-tracking cookies so websites continue to work.
Enhanced Tracking Protection protects you from ad and analytics trackers as well as cryptomining and fingerprinting trackers. Firefox lets you change your level of protection from Standard to Strict (default) or to Custom.
Enhanced Tracking Protection also clears cookies from websites you haven't interacted with in thirty days, or which are set by redirects to known tracking websites.
