About this extension
YouTube Music doesn't expose audio output routing, and Firefox's security model requires an explicit user gesture before any extension can change it. This extension bridges that gap as smoothly as possible.

On first play, a small on-screen panel prompts you to choose your output device using Firefox's native audio output selector. Once selected, routing is maintained silently across every song skip, playlist change, and SPA navigation — no repeated prompts, no interruption to playback.

Features:

One-click device selection via Firefox's built-in dialog
Automatically re-armed after song skips and playlist navigation
Selected device saved across tab reloads
Unobtrusive overlay — disappears once routing is confirmed
Scoped exclusively to music.youtube.com
