500% Volume Booster Firefox

500% Volume Booster

Boost webpage audio and video volume beyond 100% using the Web Audio API.

Features & Capabilities

🔊 Volume Booster — Firefox Extension

Push your browser audio beyond the default 100% limit — up to 500% — using the Web Audio API.
Firefox caps webpage volume at 100% natively. Volume Booster breaks that ceiling by routing all audio and video elements through a GainNode, letting you crank quiet tabs, videos, or music players to levels that are actually audible. It works on YouTube, Spotify Web, SoundCloud, and any other site that uses HTML5 <audio> or <video> elements.

✨ Features

  • 🎚️ Volume slider from 100% to 500% — smooth gain control beyond the browser default
  • 🔁 Live updates — changes apply instantly without reloading the page
  • 👁️ Works on dynamic pages — a MutationObserver catches media loaded after the page opens (e.g. YouTube)

Is 500% Volume Booster Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

500% Volume Booster requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
