Older versions
Version 3.7.1
Released Oct 26, 2026 - 494.56 KBWorks with firefox 128.0 and laterThe limiter is now an effect you can turn on and off, and it starts off. It kept loud boosts from distorting, but it could make music sound strange. Turn on Limiter under Effects to use it.
Tabs that played sound before the update ask for a reload, so the new setting applies there too.

- Feedback and help menu next to the settings button: report a bug, suggest a feature, email the developer or open help. Nothing is sent until you send it.
- Help page that explains every control and effect, in your browser's language.
- Settings lists your pinned sites with their volume. Unpin a site right from the list.
- A one-time card asks for a rating after 7 days of use.
- When VolMax is removed, a page asks what went wrong. It only receives the VolMax version and browser name.
Changed
- A reload plays at your saved volume and mute sooner.
- After an update, tabs whose volume or effects you changed keep those settings.
- The popup shows at most one prompt at a time.
- Auto Balance's tooltip and help say when it acts: only when one side stays at least 2 dB louder.
Fixed
- Media a page builds from HTML or copies, and plays without adding it to the page, follows VolMax's volume and mute.
- A copy of boosted media keeps its own volume instead of playing quieter.
- Media inside copied web components follows VolMax's volume and mute.Source code released under MIT License

Released Oct 24, 2026 - 257.26 KBWorks with firefox 128.0 and laterWhat's new since 3.0.1:
- Boosts above 100% use a limiter instead of clipping. Every step up to 1000% is louder.
- Voice boost makes speech clearer over music and effects.
- Normalize evens out loudness. Quiet videos get louder and loud ones quieter.
- Night mode lifts quiet speech and softens loud sounds.
- A "Limiting" hint by the volume number shows when more boost adds little.
- The EQ curve shows the real sound of the six bands.
- The volume slider gives 0-100% the first half of the track.
- Audio from other sites that allow it (CORS) can now go above 100%.
- The popup tells you when audio went silent and offers a reload.
- Games and web players no longer clip when boosted.
- Many fixes for hotkeys, profiles, copied media and pages with stuck frames.Source code released under MIT License
Version 3.0.1
Released Oct 24, 2026 - 233.08 KBWorks with firefox 128.0 and laterA big update since 1.7.1: a redesigned popup and a rebuilt sound engine.
New
• Live EQ curve, one-click effect chips, and a settings panel.
• Volume step: 1%, 5%, 10%, 25%, or 50% for the slider, mouse wheel, arrow keys, and shortcuts.
• Site memory: pin a site to start every visit there with your settings.
• Other tabs: switch to, mute, or reset any tab that VolMax changes.
• Works on more sites: players in shadow DOM and embedded frames, live streams, and browser games.
• The popup is available in 44 languages.
• New icon.
Changed
• The popup opens with the tab's real settings. It no longer shows 100% first.
• Lighter on every page: frames without audio or video never connect to VolMax.
• Paused pages use almost no CPU: the audio engine sleeps 30 seconds after playback stops.
Removed
• Party mode.
Fixed
• Many cases where boosted audio went silent, including live streams and audio from other sites.
• Memory leaks with detached audio players and live streams.Source code released under MIT License

Version 1.7.0
Released Apr 17, 2026 - 48.32 KBWorks with firefox 109.0 and later, android 120.0 and laterFixes volume issues on YouTube and other sites that run their own audio pipeline:
• At default settings (100%, no effects) VolMax now stays out of the way, so the site's own volume slider continues to work normally.
• When you open the popup, the slider syncs to the page's current volume, so any drag is relative to the real audio level instead of a stale 100% default.
• Volume and mute changes ramp smoothly over 50ms, removing clicks and the loud jump that could happen when the extension first engaged.
• Fixed a long-standing bug where captured audio played quieter than the page had set (the extension's gain and the native volume were both scaling the signal).Source code released under MIT License
