Latest version
Version 1.3.1
Released Nov 5, 2026 - 121.72 KBWorks with firefox 140.0 and later, android 142.0 and laterWhat's new in 1.3.1- Boost and EQ now work on Bandcamp, SoundCloud and other sites that stream audio from another domain. On Bandcamp the track reloads once, then boosts.
- Spotify: volume and mute now work. EQ, Voice and Bass are greyed out there with an explanation, because Firefox does not let extensions process DRM-protected audio.
- 100% with a flat EQ now sounds exactly like SoundSphere being off.
- Opening the popup no longer changes a tab's audio on its own.
- Lowering the volume never makes a player louder than its own setting, and resetting gives the player its volume back.
- Remembered per-tab volumes no longer carry over to unrelated tabs after a browser restart.
- Accessibility: status changes are announced to screen readers, and keyboard focus stays in the playing-tabs list.
- Lighter on busy pages.

Version 1.2
Released Dec 23, 2025 - 326.41 KBWorks with firefox 109.0 and laterAdded 10-Band EQ with presets.
More sites “just work” now: Volume boost, EQ, and presets are more reliable on sites like Bandcamp and SoundCloud.
Better behavior: Uses a “Basic Mode” when advanced boosting/EQ isn’t possible (so playback stays stable). You’ll see a clear notice when this happens.
General fixes: Smoother switching between sites and fewer cases where controls appear to do nothing.Source code released under MIT License
