Is Volume Scroll safe?

Control video volume by scrolling and customize on-screen volume feedback.

This extension lets you change the volume of videos with the mouse wheel, including finer control, optional volume rounding, and audio boost up to 500%. It can show a customizable volume overlay, add optional hotkeys for mute, play/pause, or changing scroll steps, and apply settings per site, including fullscreen-only mode and default volume or mute settings.
