      Pale Moon is an Open Source, Goanna-based web browser focusing on
      efficiency and customization.

      Pale Moon offers you a browsing experience in a browser completely built
      from its own, independently developed source that has been forked off from
      Firefox/Mozilla code a number of years ago, with carefully selected
      features and optimizations to improve the browser's stability and user
      experience, while offering full customization and a growing collection of
      extensions and themes to make the browser truly your own.
