Volume Booster With Shortcuts

Volume Booster With Keyboard Shortcuts helps boost video or music volume to up to 600%.

After installation, you can click the extension icon and control the volume using the slider, or use the toggle to turn off/on the extension.

Volume level is per tab. You can set different volume levels for different tabs.

You can use "Alt+Up" to increase the volume and "Alt+Down" to decrease the volume. Sometimes you need to click the extension icon for at least once.
