About

Plugin fingerprinting enumerates installed browser plugins via navigator.plugins (deprecated but still exposed in many browsers). Historically revealed Flash, Java, PDF readers, and multimedia codecs. Modern browsers return empty or minimal plugin arrays, but enterprise environments or users with legacy software may expose plugins. Plugin presence, order, and versions create distinctive fingerprints. Chrome extensions may expose themselves as plugins. The technique also checks navigator.mimeTypes for associated MIME type handlers. Most privacy-conscious browsers return empty plugin arrays, making plugin presence itself a signal. Legacy enterprise browsers with Java or Silverlight are easily identified.

Use Cases

•Legacy software detection
•Enterprise environment
•Plugin availability
•Browser age estimation
