Possible disadvantages of PrivacyTests.org

  • Limited Scope
    While comprehensive in areas of privacy, the site might not cover other important browser comparisons like performance or usability.
  • Technical Jargon
    Some test results may contain technical terms that are difficult for non-technical users to understand without further explanation.
  • Potential Bias
    As with any testing platform, there might be inherent biases based on the chosen metrics and evaluation methods.
  • Dependence on External Data
    Relies on external sources and privacy policies which may change, affecting the accuracy and reliability of the results.
  • Limited Audience
    Primarily targets privacy-concerned users, meaning it might not be relevant for users interested in broader browser features.

FingerprintJS features and specs

  • Unique Visitor Identification
    FingerprintJS provides a robust method for uniquely identifying users by generating a fingerprint based on their device and browser configurations. This helps in tracking user activities and preventing fraud without relying on more intrusive methods like cookies.
  • Privacy-Friendly
    Unlike cookies, FingerprintJS offers a way to identify users without storing personally identifiable information on their devices. This helps in maintaining user privacy while still achieving the goal of user identification.
  • Cross-Browser Tracking
    It allows for tracking users across different browsers and even when cookies are cleared, providing a more consistent identification method that is less affected by user actions compared to traditional cookie-based tracking.
  • Open-Source Version
    FingerprintJS offers an open-source version that can be used for free, allowing developers to integrate basic fingerprinting functionalities without incurring costs, which can be beneficial for small projects or startups.
  • Highly Accurate
    By combining multiple data points such as screen resolution, browser plugins, and timezone, FingerprintJS achieves high accuracy in differentiating users, thereby reducing the likelihood of false positives.

Possible disadvantages of FingerprintJS

  • Potential for Device Blocking
    Some users may have browser extensions or settings that actively block fingerprinting attempts, which could lead to incomplete data or inability to track those users effectively.
  • Ethical Concerns
    Even though fingerprinting is less invasive than cookies, it still raises ethical questions regarding user tracking and consent, as many users may not be aware they are being tracked in this way.
  • Performance Overheads
    Implementing FingerprintJS can introduce some performance overhead as the system must collect and process multiple data points to generate a fingerprint, which could affect loading times.
  • Complexity in Implementation
    Integrating FingerprintJS, especially the more advanced features, may require a more significant development effort and understanding of client-side data handling, which could be a barrier for smaller teams or projects.
  • Legal and Compliance Issues
    Depending on regional privacy laws like GDPR or CCPA, using fingerprinting technology may require additional consent from users, leading to legal implications if not handled properly.

  • Web fingerprinting is worse than I thought
    Https://privacytests.org Maintained by a Brave employee, though the site is fully open in all senses of the word, as far as I'm aware. - Source: Hacker News / 2 months ago
  • uBlock Origin Forcefully Removed by Chrome
    Firefox is a less bad option, even with the recent stupid policy changes they've made. Or there are a bunch of [other options that care about privacy](https://privacytests.org/), Brave, Librewolf, Arc, Zen, Orion (Kagi's thing). I tried Orion for a couple days, but it started crashing randomly and felt unstable and slowed down after real-world use (3-4 windows, many many tabs).

  • Web fingerprinting is worse than I thought
    Yeah, you get the exact same results in two separate incognito sessions in stock Chrome. They don't immediately add your fingerprint to their database. (And that site isn't using the state of the art in fingerprinting - check https://fingerprint.com/ for a slightly better indicator.). - Source: Hacker News / 2 months ago

  • Third Party Cookies Must Be Removed
    The more egregious and frankly disgusting one is https://fingerprint.com IMO this service should straight up be made illegal. I love the tagline they have of supposedly "stopping fraud" or "bots", when it's obvious it's just privacy invasive BS that straight up shouldn't exist, least of all as an actual company with customers. - Source: Hacker News / 5 months ago
