Install and pin the extension

SoundBooster works in Chrome and other Chromium browsers (Edge, Brave, Opera) that support Manifest V3 extensions.

1. Open the SoundBooster page on the Chrome Web Store and click Add to Chrome.
2. Click the puzzle-piece icon in Chrome's toolbar and press the pin next to SoundBooster, so its icon is always visible.
3. Open any tab that's playing sound and click the icon to start.

The extension has its own settings page (the gear icon in the popup) for the theme, the limiter default, the visualizer and your saved sites.
