About this extension
FoxAudioRoute allows you to easily redirect audio from HTML5 <audio> and <video> elements (like YouTube, Twitch, or Spotify Web) to specific output devices, such as a secondary monitor or a USB headset, independently of your system default settings.
Privacy Note: To prevent device fingerprinting, Firefox hides the actual names of your audio hardware by default. This extension will request a one-time, local microphone permission solely to reveal your hardware list. The microphone is instantly closed, and no audio is ever recorded, collected, or transmitted.
