You'd think that Amazon would have made it possible to control a Fire TV from external Alexa devices as soon as it was an option, but no -- you've had to use the Fire TV itself if you wanted to play a video using your voice. At last, though, sense has prevailed. Amazon has updated all versions of the Fire TV and Fire TV Stick to add support for voice control from another Alexa-enabled device. If you want to skip to the next episode of a show, you can talk to your Echo or smartphone instead of scrounging for the Fire TV's remote.
