Fingerprint Defender v2.0.0 - Blend in, don't stand out

🛡️ A privacy extension that protects against browser fingerprinting using noise
randomization instead of static spoofing.

🔄 Why v2.0.0? A New Approach

We discovered that static spoofing makes you MORE unique, not less.

Traditional fingerprint spoofers fake your browser, GPU, and screen size. The
problem? These fake values don't exist in real fingerprint databases. You become
"the only person with that exact fake configuration" - more identifiable than
before!

Our solution: Randomize what matters, pass through what doesn't.

🎯 Protection Types

🔵 Noise - Breaks cross-site tracking

• 🖼️ Canvas - Adds random pixels to canvas data. Hash changes on every domain,
  so sites cannot link your visits across the web.
• 🔊 Audio - Adds tiny variations to audio processing. Different AudioContext
  hash on every domain.
• 🔤 Fonts - Adds measurement noise to font detection. Hides OS-specific fonts
  like Segoe UI and Calibri.
• 📐 Client Rects - Adds tiny noise to element position and size measurements.

🟢 Spoof - Common values to blend in

• 🖥️ Screen - Reports 1920x1080 resolution (the most common). Your unusual
  monitor size won't make you unique.

🔴 Block - Leak prevention

• 📹 WebRTC - Completely blocks WebRTC to prevent local IP address leakage.
  Disable when using video calls.
• 🔋 Battery - Blocks the Battery Status API. Sites cannot see your battery
  level or charging status.

⚪ Pass-through - Real values to blend in

• 🌐 Navigator/UA - Your real browser and platform info passes through. You
  blend with millions of other Firefox/Windows users.
• 🎮 WebGL - Your real GPU info passes through. Avoids impossible combinations
  like "Linux user with DirectX renderer."
• 🕐 Timezone - Your real timezone passes through. Calendar apps and scheduling
  tools work correctly.
• 🔌 Plugins - Returns empty list to reduce fingerprint surface.

✨ What's New in v2.0.0

1. 🧠 Complete protection philosophy overhaul
2. 🎲 Canvas and audio randomization per domain
3. 📺 Screen resolution spoofing to 1920x1080
4. 🔤 Improved font fingerprint protection
5. 🎨 New UI with protection type badges
6. ✅ Better website compatibility
7. 🌙 Dark mode support
8. 🔍 Font size controls for comparison table

🔬 Verified Protection

Tested with Cover Your Tracks (EFF):

• ✅ Canvas fingerprint: randomized by first party domain
• ✅ AudioContext fingerprint: randomized by first party domain
• ✅ Screen size: common 1920x1080 resolution
• ✅ Browser plugins: hidden

⚠️ Known Limitations

• HTTP Accept headers cannot be modified (browser limitation)
• WebGL render hash depends on your actual GPU hardware
• Unusual hardware adds some uniqueness (rare GPU, many CPU cores)
• This is a privacy tool, not an invisibility cloak

💡 The Honest Truth

No browser extension can make you invisible. The goal is to:

• Break cross-site tracking - Sites cannot link your visits across domains
• Blend in - Look like thousands of other users, not like "the one person faking
  everything"
• Stay compatible - No more "unsupported browser" errors or broken websites

Your fingerprint is now real but common, instead of fake but unique.

🔧 Troubleshooting

• 📹 Video calls broken? Turn OFF WebRTC protection temporarily
• 🖼️ CAPTCHA failing? Turn OFF Canvas protection temporarily
• 📺 Layout issues? Turn OFF Screen protection temporarily
