LinkedFocus

A Chrome extension that blocks the LinkedIn feed to help you stay productive and avoid endless scrolling.

Features

• Feed Blocker: Hide the LinkedIn feed and replace it with a motivational message
• Focus Mode: Stay distracted-free while still accessing LinkedIn's core features
• Easy Toggle: Simple on/off switch in the extension popup
• Persistent State: Your preference is saved across sessions
• Smart Detection: Only activates on LinkedIn pages

Installation

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

Usage

1. Click the LinkedFocus icon in your Chrome toolbar
2. Toggle "Block Feed" on/off
3. Refresh your LinkedIn page to see changes
4. Use LinkedIn for messaging, job search, and networking without feed distractions

How It Works

• popup.js: Manages the extension popup UI and communicates with content scripts
• content.js: Injects blocking logic into LinkedIn pages using MutationObservers
• blocker.css: Hides feed elements and styles the replacement content
• manifest.json: Configures extension permissions and scripts

Technical Details

• Uses Chrome Storage API for persistent state

• Resource cleanup (intervals, timeouts, observers)
• Dynamic content detection and blocking

Permissions
