A minimalistic Chrome extension that blocks distracting websites so you can stay focused and productive.

• Block any website by domain (e.g. reddit.com, twitter.com)
• Blocked sites show a motivational "Stay Focused" page with rotating quotes
• Blocklist syncs across Chrome browsers via chrome.storage.sync
• Zero build step — plain HTML, CSS, and JavaScript

1. Clone or download this repository
2. Open Chrome and navigate to chrome://extensions/
3. Enable Developer mode (toggle in the top right)
4. Click Load unpacked and select this project folder
5. The extension icon will appear in your toolbar

1. Click the extension icon in the toolbar to open the popup
2. Type a domain (e.g. reddit.com) and click Block
3. The site is now blocked — visiting it will show a motivational redirect page
4. To unblock a site, click the x button next to it in the popup

The extension uses Chrome's declarativeNetRequest API (Manifest V3) to intercept navigation requests to blocked domains and redirect them to a built-in blocked page. Rules are updated dynamically whenever you add or remove a site.
