Features & Capabilities

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

🧠 Complete protection philosophy overhaul
🎲 Canvas and audio randomization per domain
📺 Screen resolution spoofing to 1920x1080
🔤 Improved font fingerprint protection
🎨 New UI with protection type badges
✅ Better website compatibility
🌙 Dark mode support
🔍 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

User Reviews

for me, even with all protections disabled, this extension breaks youtube's account button in the upper right corner. i have to manually disable Fingerprint Defender in the Firefox extension management screen.

Is Fingerprint Defender Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Fingerprint Defender requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Fingerprint Defender is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
