About Firefox Beta for Testers 121.0b8
Firefox Browser for Android is automatically private and incredibly fast. Thousands of online trackers are following you every day, collecting information about where you go online and slowing down your speed. Firefox blocks over 2000 of these trackers by default and there are ad blocker add-ons available if you want to customize your browser even more. With Firefox, you’ll get the security you deserve and the speed you need in a private, mobile browser.

FAST. PRIVATE. SAFE.
Firefox is faster than ever and gives you a powerful web browser that protects your privacy. Keep what’s personal private with Enhanced Tracking Protection, which automatically blocks over 2000 online trackers from invading your privacy. With Firefox, you don’t have to dig in your privacy settings, everything is set up automatically, but if you like to be in control, you can choose from the many ad blocker add-ons available for the browser. We designed Firefox with smart browsing features that let you take your privacy, passwords, and bookmarks with you safely wherever you go.
ENHANCED TRACKING PROTECTION AND PRIVACY CONTROL
Firefox gives you greater privacy protection while you’re on the web. Block third-party cookies and unwanted ads that follow you around the web with Enhanced Tracking Protection. Search in Private Browsing mode and you won’t be traced or tracked — your private browsing history is automatically erased when you're done.
