  • Websites waste CPU cycles and battery and Firefox lets them
    1 project | news.ycombinator.com | 15 Feb 2025
    The websites opening an audio context without using it to play anything are probably doing bot detection.

    Different browser engines and operating systems implement audio processing differently, so if you play a completely inaudible sound and then record it back (from the API not the microphone) you end up with a signature.

    You can use that signature to see if the browser is lying about its user agent, running in headless mode, or all sort of other interesting edge cases that are not a real user buying widgets.

  • Everyone knows your location: tracking myself down through in-app ads
    6 projects | news.ycombinator.com | 2 Feb 2025
    The more APIs available for JS to interact with, the more granular and detailed browser fingerprinting can be. For example, how your browser renders WebGL can differ depending on what graphics card (and drivers) you have. The resulting values can be read back and stored to create a detailed fingerprint of who you are -- this could potentially be done by Google Fonts or AdSense or any number of the countless ad and analytics frameworks loaded on basically all websites.

    Browse the source in this directory to see a plethora of examples of how web APIs are used to fingerprint users -- and this is just one publicly-accessible library we can easily review the source code of (proprietary, obfuscated ones likely use additional methods): https://github.com/fingerprintjs/fingerprintjs/tree/master/s...

  • Integrating Lighthouse Reporting in Next.js with Puppeteer and Render

    To prevent abuse, I plan to integrate browser fingerprinting and set a limit on the number of requests per client. The FingerprintJS library can generate a visitor ID to track and limit requests.
