Fast ad blocker using filter lists. Blocks ads, trackers, and popups across all websites.

A fast, lightweight ad blocker for Chrome.

Download or clone this repo 2. Go to `chrome://extensions` 3. Enable **Developer mode** 4. Click **Load unpacked** 5. Select the `extension/` folder ## How it works On install, Shield Blocker fetches EasyList and converts it to Chrome's `declarativeNetRequest` rules. These rules are applied declaratively by Chrome — no JavaScript runs on page load, making it extremely fast and efficient. ## Permissions - `declarativeNetRequest` — to block ads using Chrome's built-in engine - `declarativeNetRequestFeedback` — to count blocked requests - `storage` — to save your settings and allowlist - `host_permissions` (`<all_urls>`) — to block ads on any website
