The main projects on mobile are Firefox and Focus, on both Android and iOS. For more information about Mobile development, see the get involved page.
Focus is a lightweight browser on both Android and iOS that automatically blocks a wide range of ads and online trackers. It makes it easy to erase history, passwords and cookies, so users aren't followed by things like unwanted ads.
Bringing Firefox to mobile phones is the next step towards fulfilling Mozilla’s mission of providing access to one Web that everyone can access, regardless of device or location. The overall goals for Firefox on mobile are:
- Deliver an exceptional mobile experience to users, complete with the performance, personalization and security they expect.
- Do all of this work in the shared Mozilla source repositories so all platforms, desktop and mobile, benefit each other.
The recommended way to install Firefox for Android is from the Google Play Store: https://play.google.com/store/apps/details?id=org.mozilla.firefox. You can download older Firefox for Android APKs for testing from https://archive.mozilla.org/pub/fenix/releases/.
GeckoView is Firefox's engine, packaged as a reusable Android library.
The blog post Firefox Focus with Gecko View provides some additional background on GeckoView's development.
