All Fingerprint Defender

Stable per-site fingerprint defense for Canvas, WebGL, Audio & fonts. Sites keep working, and nothing leaves your browser.

Every site you visit quietly measures your browser — how it draws graphics, renders 3D, plays audio, and spaces out fonts — and blends those details into a "fingerprint" that can follow you around the web, even in incognito, even without cookies. All Fingerprint Defender shows each site a stable, believable fingerprint instead of your real one. Turn it on once and it just works, quietly, in the background. No account, no setup. WHAT'S NEW IN THE REBUILD Older tools (this extension's own v1 included) threw fresh random noise at every read. It sounds strong, but it backfires: trackers flag a canvas that changes twice on one page as bot-like, the constant redraw can break sites, and looking brand-new on every load can make you MORE unique. v2 takes the calm approach — stable, per-site protection. Each site sees ONE consistent fingerprint for your session, so pages keep working and you're not flagged for "drawing twice," while different sites and different sessions never match, so your activity is hard to link from place to place. The default noise is sub-perceptual. WHAT IT PROTECTS • Canvas 2D • WebGL, including the graphics-card vendor and renderer strings • Web Audio • Font metrics All in one extension. YOU STAY IN CONTROL ✓ Pin this site — lock a fingerprint for logins and banking so it never shifts ✓ New fingerprint — re-roll every non-pinned site at once with one click ✓ Pause for a site — turn protection off for one misbehaving site, applied instantly ✓ Standard mode (sub-perceptual, recommended) or Aggressive mode (stronger) ✓ A quiet dashboard shows how many fingerprint attempts were handled, on which sites, and which methods were used PRIVATE BY DESIGN Nothing leaves your browser. No external network calls, no analytics, no account. It does NOT request the "read your browsing history" permission. VERIFY IT YOURSELF (2026) Try these with protection on and off: • browserleaks.com/canvas • browserleaks.com/webgl • browserleaks.com/fonts • creepjs • iphey.com Honest about what it is: a browser extension, not an anti-detect browser or a VPN. It reduces linkability and raises the cost of fingerprinting — it won't hide your IP or make you "100% anonymous." Calm, quiet protection for everyday Chrome and Edge (Manifest V3), the kind you can leave on all day.
