About this extension
NahNotToday Privacy & Security
Take back control of your browser fingerprint. NahNotToday answers the main tracking vectors with noise that holds still for the whole session: every reload shows a site the same thing, with no random flicker in between.
One-click profiles:
Generate a complete, internally consistent profile — GPU, fonts, resolution, locale, time zone and CPU thread count, all matched to a real OS and browser. Or set every value by hand.
See what was probed:
The Information tab lists every vector the site actually touched, and what it received in place of your data. Not a green checkmark — the value itself.
Always on:
• Canvas fingerprint
• WebGL vendor and renderer
• WebGPU adapter
• AudioContext fingerprint
Your choice, per setting:
• User-Agent string
• Browser languages
• Screen resolution
• Time zone
• Font enumeration
• Client Rects — element geometry
• Speech synthesis voices match the spoofed system
Additional protection:
• Ad and tracker domain blocking
• Third-party cookie blocking (off by default — it is a browser-wide setting)
• WebRTC IP leak protection: your real address never reaches the page, and calls keep working
Whitelist for trusted sites — add the current site with one click and fingerprint spoofing stops there.
Nothing leaves your browser:
• Everything runs locally — no cloud, no servers
• No logs, no data collection, no telemetry
Verified against CreepJS, BrowserLeaks and WebBrowserTools: the noise stays the same within a session and changes between sessions.
Pair it with a VPN so your time zone and your IP tell the same story.
