Stop browser fingerprinting. Persistent noise for Canvas, WebGL & AudioContext. Ad & tracker blocking. No logs, no servers
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.

- Is there a way to temporary disable to pass cloudflare, and reload the options once its done?
- transcendreamer
- Not bad! But resolution spoofing breaks some page formatting (e.g. Gmail, Gemini).
- Noche Hughes
- I like the idea, and it has been implemented well. One thing that could be added to make it more robust is for the timezone and location parameters to change whenever the VPN IP changes.
- かみかつき
- It seems that it can't pass Cloudflare Challenger if you turn on everything. It also causes the channel point box and drops can not be claimed on Twitch even whitelisted.
- jhon laman
- it causes some websites block my visit. some of them i remember is https://www.amiunique.org/fingerprint please fix it sir.. thank you..
- Manfredi
- Great extension for privacy, works fine in Edge too. It would be nice if there was a whitelist to disable the extension on specific websites, because Spotify web player and others seem broken even with the minimum protection settings.
