Released Sep 10, 2026 - 114.1 KBWorks with firefox 142.0 and laterWhat's new in 1.5.0
New look
• 12 accent colours to pick from, including Azure, Teal, Orange and Fuchsia
• 5 background styles: Midnight, OLED Black, Graphite, Nebula and Dusk
(OLED Black is pure black and saves battery on OLED screens)
• Colours and backgrounds are set separately, so you can mix any combination
• A new Appearance window keeps everything in one place, with four
quick-pick colours right in the settings
Better visualizers
• Redesigned from the ground up — they now follow the music properly
instead of barely moving
• Bass, mids and highs each get their own space, so beats are clearly visible
• The picture adapts to how loud the tab is: it stays lively on quiet videos
and never flattens out on loud ones
• New Bass Bloom visualizer that pulses with the low end
• Removed the old Pulse Bar
More languages
• Now available in 18 languages, including Hindi, Arabic, Vietnamese,
Indonesian, Japanese, Korean, Chinese, Turkish, Dutch and Polish
• Right-to-left layout support for ArabicSource code released under All Rights Reserved
Version 1.4.2
Released Aug 25, 2026 - 68.32 KBWorks with firefox 142.0 and laterWhat's new in 1.4.2:
• Fixed: on Firefox, the booster could switch on but play no sound in some cases — audio now starts correctly the moment you boost.
• Improved: "Auto-Boost" is now more predictable. If your browser needs one click on the icon before it can boost automatically, it tells you so instead of silently doing nothing — and the option's description now clearly explains how it works.Source code released under All Rights Reserved
Version 1.4.1
Released Aug 14, 2026 - 66.94 KBWorks with firefox 142.0 and laterWhat's new in 1.4.1:
• Fixed: SoundCloud and other music streaming sites are now boosted correctly. These players create their audio "invisibly" (outside the page); SuperVolume now detects and attaches to them automatically.
• Fixed: players created only after you press Play are now picked up on the fly — no page reload needed.
• New: if no media is playing yet, the popup shows a friendly hint instead of doing nothing silently.Source code released under All Rights Reserved
Version 1.4.0
Released Aug 14, 2026 - 65.15 KBWorks with firefox 142.0 and laterWhat's new in 1.4.0:
• Night Mode — one switch flattens loud scenes, lifts quiet dialogue and cuts low rumble. Perfect for late-night watching.
• Auto-Gain — automatic loudness normalization: every video plays at the same comfortable level, no more reaching for the volume.
• Keyboard shortcuts — Alt+Shift+S toggles the boost, Alt+Shift+Up/Down changes volume by 25% (customizable in the browser's shortcut manager).
• Boost up to 1000% — new "Maximum" level, kept clean by a built-in soft-clip limiter instead of harsh digital distortion.
• All-new "Aurora" design — bigger window, glass cards, neon gradients and a smoother visualizer.
• Settings page — manage every saved site (volume, modes, auto-boost) in one table, opened right from the popup.
• Fixes: mono downmix verified, CORS-protected media is now detected and reported instead of muting, smarter update handling.Source code released under All Rights Reserved
Version 1.3.0
Released Aug 6, 2026 - 45.86 KBWorks with firefox 142.0 and laterWhat's new in 1.3.0:
• Per-site memory — SuperVolume now remembers your volume, equalizer and settings for each website and restores them automatically.
• Smart Volume Leveling — a gentle compressor tames loud ads and sudden explosions and lifts quiet dialogue.
• Visualizer skins — choose between Holographic Wave, Retro LED Spectrum and Pulse Bar.
• New languages — the interface is now available in English, Russian, French, German and Spanish, with automatic language detection.
• Stability and performance improvements.Source code released under All Rights Reserved
