About the app

Everything you need to know about Firefox: Private Web Browser.

Description

Take control of your internet experience with Firefox. When you choose Firefox, you choose privacy, focus, and a better way to browse. PRIVACY WHERE IT COUNTS Firefox blocks hidden trackers that follow you online and slow things down. Want more control? Switch Enhanced Tracking Protection to Strict mode for stronger defense across all your tabs. Or use a private window — your search and browsing history automatically disappears when you close all your private tabs. STAY IN SYNC, WHEREVER YOU BROWSE Start a search on your phone, pick it up on your laptop — or vice versa. With a Mozilla account, your open tabs, history, and bookmarks stay in sync. Firefox can also suggest strong passwords when you create an account, and store them securely so they’re available on every device. A SMARTER HOME SCREEN Jump right back in. Your open tabs are grouped automatically, along with your recent bookmarks, top sites, and popular articles — all in one place. FIND WHAT YOU NEED FAST Get smart suggestions as you type and quickly access your most-visited sites and past searches from your favorite search engines. TABS, YOUR WAY Open as many tabs as you need without losing your place. Firefox shows them as thumbnails, so it’s easy to jump back to what matters. SHARE IN SECONDS Easily share links or specific parts of a page, with quick access to your most recently used apps. BILLIONAIRE-FREE FOR OVER 20 YEARS Launched in 2004, Firefox was built by Mozilla as a faster, more private, more customizable alternative to other browsers. Today, we’re still not-for-profit, still independent — and still working to make the internet, and the time you spend on it, better. Learn more about Mozilla at https://www.mozilla.org.
