Blur Ads on LinkedIn (Unofficial)

English | 中文

Visual helper that softly blurs sponsored items on LinkedIn. It does not bypass LinkedIn’s advertising systems.

Features

• 🚫 Visual Blur for Promotions: Detects promoted job cards, feed updates, and banner units, then applies a blur overlay to reduce distraction.
• 🎚️ Adjustable Intensity: Change the blur strength (2-15px) directly from the popup.
• 🔄 Real-time Updates: Mutation observers keep newly loaded content blurred as the LinkedIn SPA updates.
• 🧭 LinkedIn Surfaces Covered: Runs on feed, jobs, messaging, My Network, notifications, profiles, and other LinkedIn pages when enabled.
• 📴 Quick Toggle: Turn the blur effect on or off at any time from the popup.

Unofficial & Privacy Notice

How It Works

1. Content Detection: The extension scans LinkedIn pages for promoted content using:

   • Text analysis for the configured promotional keywords
   • DOM attribute checks for ad-specific markers
   • LinkedIn-specific selectors for job cards and feed posts

2. Blur Application: When promotional content is detected:

   • A blur filter is applied with the intensity you've chosen
   • An optional indicator can be shown when the showIndicators setting is manually enabled
   • Hovering temporarily reduces the blur so you can preview the hidden content

3. Dynamic Updates: The extension uses mutation observers to:

   • Detect newly loaded content (infinite scroll, SPA navigation)
   • Process dynamic content updates
   • Maintain consistent visual filtering across page changes

Advanced Configuration

Settings are stored in Chrome sync storage. Developers can manually adjust values such as showIndicators, activePages, or custom keyword lists by editing the stored settings (e.g., via the background console) and reloading the extension.

Development

1. Make your changes to the source files
2. Reload the extension in chrome://extensions/
3. Test on LinkedIn pages
4. Submit a pull request

Testing

• Test on different LinkedIn pages (jobs, feed, profiles)
• Verify functionality with different languages
• Check performance with large pages
• Test settings persistence across browser sessions
