Firefox Preview

Mozilla already has the regular Firefox Internet browser on Android, and it’s a proper application, but it’s not something built specifically for this platform. Mozilla is building a new browser that’s more efficient and which should prove to be a great replacement.
 
Firefox Preview is still under development, and not all the features are implemented. It’s built on GeckoView, and it’s faster than ever. It also features an incognito mode that’s just one tap away. Other features available include multiple tabs, tracking protection, a dark theme, and support for various search engines.
 
Please keep in mind that Firefox Preview is not a stable Android application.
