About this extension
Vol Boost lets you increase the volume of any tab beyond the default system limit — up to 600% amplification.

Features:
- Simple slider control from 0% to 600%
- Quick preset buttons: 0, 100, 200, 400, 600
- Settings are saved and restored automatically
- Works on any website with video or audio content
- Lightweight — no tracking, no data collection

Useful for videos with low audio, conference calls, music streaming, or any situation where the system volume isn't enough.

(Note for Android: Audio may pause briefly when the extension connects to a media source for the first time on a page.)
