The Firefox browser for Android is automatically private and incredibly fast. Thousands of online trackers follow you every day, collecting information about where you are going online and slowing down your speed. Firefox blocks more than 2,000 of these trackers by default, and ad blockers are available if you want to further customize your browser.
