How It Works

rules.json

Uses Chrome's Declarative Net Request API to block requests sent to common advertising endpoints.

Examples include:

• /api/stats/ads
• /pagead/
• doubleclick.net
• googlesyndication.com

---

content.js

A MutationObserver watches YouTube for changes and automatically:

• Clicks Skip Ad
• Mutes advertisements
• Speeds up unskippable ads
• Removes overlays and banners

---

popup.html & popup.js

Provides a simple On/Off switch.

The selected state is stored with chrome.storage.local, so it persists between browser sessions.
