Firefox is known for private browsing, tracking protection, and faster page loading. With Private Browsing, the browser blocks online trackers and clears your search and browsing history when you’re done. Built-in tracking protection blocks third-party content that tracks you as you surf the web. The performance benefit of tracking protection is up to 44% faster page load times.
Firefox is highly customizable with thousands of extensions, themes, and a drag-and-drop toolbar. With a Firefox account, users have the option to sync settings, passwords, and bookmarks across all of their devices. Multi-account containers are unique to Firefox so users can separate their personal, work and shopping browsing without the need to log out of accounts or switch browsers. With up to 30% less memory usage than Chrome, Firefox is very fast.
