What’s the difference between Firefox Preview and Firefox for Android?

Firefox Preview is an early version of an experimental Firefox browser for Android. Built on GeckoView, it is a pilot for early adopters, developers and anyone who wants to help make a better, more private Firefox for Android.

Firefox Preview is the first step in building a new mobile browser that’s faster than any mobile Firefox before it. It will combine the speed, privacy, control, and easy-to-use features you come to expect from Firefox.


We've added a Collections feature to help you group and organize tabs for later use.

Tracking protection by default

Firefox Preview’s tracking protection blocks ad trackers that follow you around the web and tracking scripts that can slow down your browsing. It’s on by default in both normal and private browsing mode. If tracking protection breaks site content or functionality, you can turn it off for that site it by tapping the tracking protection icon in the address bar and disabling it in the panel that appears.
