As long as your Fire TV is on a secure network, there’s no harm in keeping ADB-Debugging on all the time. One caveat is that you must keep ADB-Debugging enabled within the Fire TV’s settings in order for FireStarter to work correctly.

To install FireStarter, simply download the latest APK and sideload it as you would any other app. It’s not perfect, but it works extremely well and reliably. It can’t actually stop the default homescreen from launching, which is why you will see it very briefly flash on the screen when you press the home button, but your configured application/launcher will launch a split second later. Using this log monitoring method, FireStarter can even detect if you double-click the Home button. FireStarter cleverly monitors the Fire TV’s log output to know when the Home button has been pressed, and then launches itself, or any application you configure it to launch. It will always launch the default homescreen. There is no way, without rooting the device, to change what happens when you press the Home button on a Fire TV or Fire TV Stick remote.
