Scroll Volume

A Chromium MV3 extension built to be my ideal scroll-to-volume controller with robust context detection and site controls.

  • JavaScript
  • Chrome Extension API
  • Manifest V3

Scroll Volume is a browser quality-of-life tool built for fast, consistent media control.

Goal

Build the exact scroll-volume extension I always wanted, using AI agents to accelerate development and iteration.

Hardest challenge

Deciding when wheel input should control video volume versus when it should pass through to normal page scrolling while hovering media.

Outcome

Published to both the Microsoft Edge Add-ons store and the Chrome Web Store.
