A:Answer Yes, you can plug in a Firestick. There are 3 HDMI ports. You'll need to use one of them for your cable service, if applicable. Use the remaining 2 for whatever (Apple TV, Firestick, Chromecast, etc.) The TV already has Prime Video loaded. The Apple TV is loaded too. It's a pay/view channel. I have a Firestick on mine because I wanted the Prime Music also.
