Support

If you have questions or trouble with Firefox for mobile, please see our dedicated Mobile Support site.

Download Firefox Beta

Install Firefox Beta if you want to help us test the next version of Firefox for Android. Firefox Beta contains new features and changes that are ready for widespread testing before we include them in the next official Firefox release. You can install both Firefox and Firefox Beta at the same time if you want to use both versions. Download instructions: Check the system requirements below to see if Firefox Beta is compatible with your Android device. Install Firefox Beta from the Google Play Store. You can also download the APK directly from our FTP server. If you download Firefox beta from the FTP server, you will need to update it manually when a new version is released. Firefox Beta is also available for other platforms! Go to firefox.com/channel to learn more and download Firefox Beta for your computer.

Download Aurora

If you want to test upcoming changes to Firefox before they reach the Beta channel, you can download a build from the Aurora channel. If you want to, you can install Aurora alongside the official released version of Firefox, and use both on the same device. The Aurora channel provides an early preview of the next Firefox Beta release. Although Aurora builds are more stable than our nightly development snapshots, they are not yet fully tested like our official beta and release versions. Aurora will offer to update itself automatically about once a day, as we make improvements and fixes. Download instructions: Check the system requirements below to see if Aurora is compatible with your Android device. Open mozilla.org/mobile/aurora in any web browser on your Android device, and click the link to download Aurora directly to your device. Open the "apk" file when it finishes downloading.

Download Nightly

If you are actively developing or testing Firefox features that are not yet released to the Aurora or Beta channels, you can download a Nightly build. You may install and use Nightly alongside builds from other channels (Firefox, Beta, Aurora). The nightly channel is a snapshot of our very latest development work, before it is ready for widespread testing. This is our least-stable test channel. Nightly will offer to update itself automatically about once a day with the latest changes from our developers. Download instructions: Check the system requirements below to see if Nightly is compatible with your Android device. Open nightly.mozilla.org in a web browser on your Android device, and press the link to download the Android nightly build directly onto your device. Open the "apk" file when it finishes downloading.
