We are thrilled to bring you Privacy Guard v0.14.0! This major update introduces powerful new anti-tracking shields, real-time


sensitive data leak protection, clean link sharing, and an instant search bar in the popup.

---

### 🚀 What's New

#### 1. 🔍 Instant Feature Search in Popup
- Find and toggle any feature instantly with our new smart search bar located directly in the popup header.
- Supports multi-keyword search, Vietnamese & English diacritics-insensitive matching, and scope filters (`fb`, `ig`, `global`).

#### 2. 🛡 Chat Input PII & Secret Leak Shield
- Automatically detects sensitive personal identifiable information (PII) and secret credentials pasted into chat input boxes:
- Credit Card / Debit Card numbers (with Luhn checksum validation)
- Vietnamese CCCD / CMND identity cards
- Developer API Keys & Secrets (OpenAI `sk-proj-*`, Google AIza, GitHub PAT, AWS keys, JWT tokens, RSA private keys)
- Provides an immediate, non-intrusive on-screen prompt giving you the choice to paste safely masked text or cancel before accidental


transmission.

#### 3. 🔗 Clean Share Links
- Automatically strips tracking parameters (`fbclid`, `igshid`, `utm_*`, `mibextid`, `ref`, and more) when copying links from


Facebook and Instagram posts, reels, and stories.
- Ensures the links you share are clean, concise, and protect recipient privacy.

#### 4. 🎭 Canvas & WebGL Anti-Fingerprinting Shield
- Defends against browser and device fingerprinting by Meta and third-party trackers.
- Normalizes canvas data with micro-noise and standardizes hardware concurrency, device memory, and WebGL renderer signatures without


breaking website layout or functionality.

#### 5. 📡 Updated Meta Telemetry & Dwell Signatures
- Upgraded suppression patterns for modern Facebook & Instagram telemetry beacons, feed dwell-time monitoring, and heartbeat tracking


payloads.

### ⚡ Improvements & Bug Fixes
- **Smooth Popup Experience**: Resolved scroll cutoff issues, eliminated toggle jitter/flicker, and prevented unexpected scroll jumps


when toggling features.
- Code Quality & Reliability: Upgraded test suite with 67 test suites (653 passing tests) and 100% green CI pipeline on Node.js
22 & Manifest V3.
