K-Meleon is a lightweight, customizable, open-source web browser. It's designed for Microsoft Windows (Win32) operating systems. K-Meleon can use the secure Goanna engine based on Mozilla's Gecko layout engine or Gecko itself. The popular web browser Firefox also uses Gecko. K-Meleon runs on legacy hardware and operating systems that other modern web browsers no longer support.
