The installation is pretty easy. You simply have to download the app from the Amazon Appstore and send it to your chosen Firestick. It should be directly installed and you can find the icon on your TV. If it’s not there, it should be in your Amazon cloud space. You can click the icon there and it will be installed automatically. You can also automatically protect wi-fi networks with CyberGhost for Amazon Fire TV/Fire Stick, or you can adjust specific reactions to known Wi-Fi networks.
