About Volume Booster

Volume Booster gives your browser the extra kick it needs. Tired of quiet videos or streams that never seem loud enough Even when your system volume is maxed out, this extension raises the playback volume inside the tab and lets YouTube and Twitch live streams go truly fullscreen — the kind of fullscreen other extensions struggle to deliver. It’s lightweight, fast, and built for people who want better sound and a distraction‑free viewing experience.
