NahNotToday is a browser extension designed to counter browser fingerprinting and enhance privacy for users of Chrome and Firefox. By introducing persistent, session-based noise across key fingerprinting vectors, the tool aims to prevent tracking networks from assembling a stable, unique identity based on a user's device and browser characteristics. Unlike traditional privacy measures that focus on cookies or IP addresses, NahNotToday targets the technical signals—such as GPU details, installed fonts, screen resolution, and more—that are combined to form a fingerprint that can identify users across sessions, sites, and even private browsing modes.
The extension actively spoofs several fingerprinting vectors. It injects subtle, stable noise into every canvas read, spoofs WebGL vendor and renderer strings, masks the unique signature of the user's audio stack, and blocks font enumeration. For client rects, it adds geometry jitter to prevent sub-pixel measurements from betraying unique font rendering. Users can generate a new, internally consistent identity profile in one click, with coordinated values for GPU, fonts, resolution, locale, and time zone, all matched to typical OS and browser pairings. Alternatively, users have the option to manually override and fine-tune these values, including user-agent, languages, resolution, and time zone, to better match their VPN exit node or specific privacy needs.
NahNotToday operates entirely locally within the browser, with no servers, logs, or telemetry involved. All spoofing and noise generation occur client-side, so no data leaves the user's device. The extension does not require account creation or complex setup; installation from the Chrome Web Store or Firefox Add-ons is sufficient, with sensible defaults applied immediately. A simple popup interface informs users of current spoofing status, and individual sites can be whitelisted if needed.
Beyond fingerprint spoofing, the extension also blocks third-party cookies and disables WebRTC to prevent IP leaks, addressing privacy gaps that VPNs and standard browser settings may overlook. NahNotToday has been tested against industry-standard fingerprinting test suites, passing major checks and maintaining consistent, believable identities across sessions. The tool is positioned as a privacy and security solution for users seeking to minimize online tracking and maintain control over their browser fingerprint.
In the Security & compliance platforms space, NahNotToday takes a focused approach. It focuses on preventing online tracking and browser fingerprinting to protect user privacy. NahNotToday is a consumer product aimed at privacy-conscious web users. NahNotToday costs nothing to use. It runs on the web and embeddable surfaces.
NahNotToday first shipped in 2026. Across PulseGate's embedding index, NahNotToday has few near neighbours, marking it as relatively distinct. Among its 7 catalogued features are fingerprint spoofing, canvas protection, and webGL protection.
