Turning on Apps from Unknown Sources on an Amazon Fire TV, Firestick, Fire TV Cube, or Fire TV Smart TV allows you to sideload app APKs onto the device from within another app, like Downloader. These instructions show you how to find Developer Options and allow the installation via side loading.

This guide was originally published in 2015 but has been updated in 2022 to include instructions for new Fire TV models, the new interface, and for devices with Developer options hidden.

2020 Interface (Latest)

If the main navigation menu on your Fire TV home screen is in the center of the screen, then your device has the 2020 interface and you may continue to the first step. Otherwise, if the main navigation menu on your Fire TV home screen is at the very top of the screen, scroll down to the 2015 interface section below.

 

1. From the Fire TV home screen, scroll to Settings, which is the gear icon on the far right of the main navigation menu.
