Tracking generally refers to the collection of a person’s browsing data across multiple sites. The Firefox Preview Enhanced Tracking Protection feature uses a list provided by Disconnect to identify and block 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.
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.
