    Not all content is supported by the Chromecast, therefore, you have to ensure the content you want to cast is supported.

How to Cast From Firefox on Windows, macOS, and iOS

You'll have to use a workaround for this to work. Despite Firefox being supported on Windows, macOS, and iOS the cast functionality is not supported on these operating systems. However, you can always use an Android emulator to run a virtual Android device on your Windows or Mac device. Once you have set up the Android device on the emulator you can proceed with the steps above.

Make sure the Android device is connected to the same network as your Google Chromecast device.
