Calling all Mozillians! Download the new Nightly for Android! 

Firefox for Android is extremely important to Mozilla’s mission. We are delivering an exceptional mobile Web experience for users, with the performance, personalization and security they expect. We are also providing developers a platform to keep the mobile Web open by establishing Gecko as a top-tier mobile Web platform on Android. And we do all of this work in the shared Mozilla source repositories so all platforms, desktop and mobile, benefit each other.

Mozilla is embarking on the ambitious target to re-architect Firefox using a native Android user interface. This evolved product will deliver improvements to start-up time, memory usage, UI responsiveness and battery usage. Our plan is very ambitious, and will require everyone’s help and efforts for success.

In a short period of time, we have made enormous progress and have quite an exciting experience already; but the mobile development team really needs more bugs filed so testing Nightlies in the meantime is ever more crucial to the product’s development. Nightly builds are generally used by developers and contributors who build and test Firefox to verify and test bugs. Nightly users should expect exciting changes with every update, as well as instability, possible regressions, and many bugs. Nightly users now can already feel the drastic differences from XUL-based Firefox, and identifying more bugs is critical to continue improving the product.

Get involved!

We urge all Mozillians to download a Nightly build to help file bugs and provide feedback.


Need a supported Android phone? Tell us here. We may not be able to give a device to everyone, but will keep your name on file for when devices are available.

Download the latest Nightly .apk file from the Android section. Users will need to allow the installation of non-Market applications (depending on device: Preferences > Applications). Devices will also need around ~13MB of application space, check if your device is supported here. You should only need to download from the Birch tree once, updates will show in your Android notification status automatically.

Find Bugs

Try to use the Nightly build as your default browser as much as you can. Help us test these features and make sure they work properly and well.  If not, file a bug!

File Bugs

Go to Bugzilla and include the device name/Firefox version/OS version, steps to reproduce, and the expected and actual outcomes (Bugzilla 101 video). It would also be helpful if you could attach a screenshot of your issue (take screenshots without rooting your phone or enabling x11). Also see known issues for reference, but please do file the bug anyway if you are not sure.

Fix Bugs

See our Get Involved wiki to learn how, and join the Android Nightly Testers mailing alias for questions, discussions and news.
