Open it in the Silk browser
Every Fire TV device ships with Amazon's Silk browser. Open Silk, type this address with the remote, and CyberFlix loads in its television layout: large posters, the service catalogs across the top, and the search box ready for the remote's keyboard or voice. Add it to Silk's bookmarks and it is one click from the home screen.
Downloader codes
Many Firestick users know CyberFlix from the Downloader app and its short codes. The browser route replaces both: there is nothing to sideload, the catalog updates itself, and the Watch now button hands each title to the service's own Fire TV app, Netflix, Prime Video, Disney+ and the rest, all installed from the Amazon Appstore.
Android TV boxes and Superbox
On an Android TV box, including the Superbox models, open the address in the box's browser, or cast it from a phone with Chromecast. The devices page covers the rest.
