What is Browser Fingerprinting?

How does browser fingerprinting work?

Understanding browser uniqueness

Improving browser uniqueness

  • Use a commonly used browser. Running odd browsers (e.g., Comodo IceDragon) will greatly increase the likelihood of having a unique fingerprint.
  • Avoid custom user agents. Unique user agents are a surefire way to stand out from the crowd.
  • Reduce the amount of plugins used. Uniqueness is severely impacted by the amount of plugins installed in a browser.
  • Narrow down the preferred language list. Requesting pages for different languages greatly increases browser fingerprintability. For example, TorButton requests only EN versions of websites by default.
  • Use TorButton. TorButton implements most of the security features used in Tor Browser to a Firefox browser.
  • Disable JavaScript. Disabling JavaScript is an extreme measure that will break almost all websites. Yet, EFF finds that NoScript (an extension that allows users to switch off JavaScript) users were the most resistant to fingerprinting.
