About Firefox Beta for Testers 40.0
From version 152.0b8:
Premium
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.
OWN YOUR LIFE WHEREVER YOU INTERNET
- Add Firefox across your devices for secure, private and seamless browsing.
- Sync your devices to take your favorite bookmarks, saved logins and browsing history wherever you go.
- Send open tabs between mobile and desktop.
- Firefox makes password management easy by remembering your passwords across devices.
- Take your internet life everywhere, knowing that your personal data is safe, never sold for profits.
SEARCH INTELLIGENTLY & GET THERE FASTER
- Firefox anticipates your needs and intuitively provides multiple suggested and previously-searched results across your favorite search engines. Every time.
- Easily access shortcuts to search providers including Wikipedia, Twitter and Amazon.
NEXT LEVEL PRIVACY
- Your privacy has been upgraded. Private Browsing with Tracking Protection blocks parts of Web pages that may track your browsing activity.
INTUITIVE VISUAL TABS
- Open as many tabs as you like without losing track of your open Web pages.
EASY ACCESS TO YOUR TOP SITES
- Spend your time reading your favorites sites instead of looking for them.
QUICK SHARE
- The Firefox web browser makes it easy to share links to web pages or specific items on a page by connecting to your most recently used apps like Facebook, Instagram, Twitter, WhatsApp, Skype and more.
TAKE IT TO THE BIG SCREEN
- Send video and Web content from your smartphone or tablet to any TV equipped with supported streaming capabilities.
BILLIONAIRE FREE FOR 20+ YEARS
The Firefox browser was created in 2004 by Mozilla as a faster, more private browser with more customizable features than web browsers like Internet Explorer. Today, we are still not-for-profit, still not owned by any billionaires and still working to make the internet — and the time you spend on it — better.
