A glowing blue light indicates that your FireStick remote’s Alexa Voice function is active and listening to you. Press the Alexa Voice button on the FireStick remote to turn this off. There is also another way for you to know when Alexa is listening to you via FireStick. Open the Alexa app on your device; head to “Settings,” then “Alexa Privacy” and then select “Review Voice History.” This will show you all the instances when Alexa has been listening to you and recording your audio.
