Someone’s browser is

The Open Book

Websites can read you like a book.

What’s yours? Take the test

You browse without a disguise, and your combination of settings is distinctive enough to pick out of a crowd. Sites don’t need cookies to recognize you when you come back — your screen, graphics card, time zone and language do the job.

What you can do

  • Use a browser with built-in fingerprinting protection, such as Brave or Firefox with strict tracking protection.
  • Avoid rare extensions, fonts and settings that make your browser stand out.
  • Keep your browser updated — an outdated version is a rare signal on its own.
