Earful Bridge by AidarDev

Requires Earful for GNOME (Linux). Install it with one command:
curl -fsSL https://raw.githubusercontent.com/NGdev2/earful/main/install.sh | sh

Three tabs playing, and your desktop only sees the last one. Earful Bridge fixes that.

Every tab that plays music or video becomes its own player on your GNOME desktop. Each one gets its own row in the Earful top bar menu: title, artist, cover, play, pause, next and a volume slider. Click a row and Firefox jumps to that tab.

Where it helps
- A playlist in one tab, a podcast in another. Pause the right one without hunting for it.
- Music while you work. Skip a track from the top bar and stay in your editor.
- Who sings this? A small popup shows the song when the track changes.

The tabs also show up in GNOME's own media controls and in playerctl (through MPRIS on D-Bus).

What Earful adds
- One menu for every player: Spotify, VLC, podcast apps and browser tabs.
- A popup with cover, title and artist when the track changes.
- Designs: gradient, dark glass, vinyl, sound wave, retro equalizer, note road, cassette.
- Focus mode (Super+Shift+M) silences popups. No popups over fullscreen or in Do Not Disturb.

Good to know
- Next and previous work on sites that support media keys: YouTube, YouTube Music, Spotify, SoundCloud and most music sites.
- Firefox from Snap (Ubuntu's default) asks once whether Firefox may start Earful's helper. Choose Allow. Firefox from Flatpak can't start it.
- Tabs that were open before you added the add-on need a reload.
- Right after you add it, the add-on checks for Earful. If Earful is missing, it opens a page that shows how to install it.
