Hi There is not a version of Firefox for Android available for the Amazon products, but there is a way that you can download it and use it on your device. In the system or settings app on your device, you will need to find the setting to allow the device to install software from unknown sources. You will then need to consider carefully and download the file for the version of Firefox for Android you want to use using your mobile device. The full release version of Firefox for Android (available [https://ftp.mozilla.org/pub/mobile/releases/42.0.1/android-api-11/en-US/fennec-42.0.1.en-US.android-arm.apk here]) will not automatically update. You will need to manually download new versions (this may overwrite any bookmarks and settings you have saved). Firefox Beta for Android (available [https://ftp.mozilla.org/pub/mobile/releases/43.0b7/android-api-11/en-US/fennec-43.0b7.en-US.android-arm.apk here]) will not automatically update. You will need to manually download new versions (this may overwrite any bookmarks and settings you have saved). This is not a finished product but is more stable than Firefox Aurora for Android. Firefox Aurora for Android (available [https://ftp.mozilla.org/pub/mozilla.org/mobile/nightly/latest-mozilla-aurora-android-api-11/fennec-44.0a2.multi.android-arm.apk here]) will automatically update, but is a less polished version of Firefox Beta for Android, so may contain some bugs. (There is a version that is at an even earlier stage of production, Firefox Nightly for Android, but this is significantly less stable and is very much an unfinished version of the browser.) Once downloaded, it will either open automatically, or you will need to open it using a file explorer type app. This is a very non standard fix, but I hope that this helps.

What an awesome answer! Very informative and complete! Thank you for giving me all of the information I need to make a good decision.
