There is an option on Fire TV and Fire TV stick that prevents the installation of third-party programs. Before you can install Kodi on a Firestick, you must first modify this option. Click on the Settings option after turning on your fire TV. You can then access the system menu this way. To access the developer settings, scroll below. Switch on the "apps from unknown sources" button here. Verify your want to install from untrusted sources. You can now install Kodi on a Firestick or Fire TV after getting things under control.
