Pale Moon is an Open Source, Goanna-based web browser available for Microsoft Windows and Linux (with other operating systems in development), focusing on efficiency and ease of use.

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.

This browser, even though fairly close to Gecko-based browsers like Mozilla Firefox and SeaMonkey in the way it works, is based on a different layout engine and offers a different set of features. It aims to provide close adherence to official web standards and specifications in its implementation (with minimal compromise), and purposefully excludes a number of features to strike a balance between general use, performance, and technical advancements on the Web.


  • Optimized for modern processors
  • Based on our own optimized layout engine (Goanna)
  • Safe: forked from mature Mozilla code and regularly updated
  • Secure: Additional security features and security-aware development
  • Supported by our user community, and fully non-profit
  • Familiar, efficient, fully customizable interface
  • Support for full themes: total freedom over any element's design
  • Support for easily-created lightweight themes (skins)
  • Smooth and speedy page drawing and script processing
  • Increased stability: experience fewer browser crashes
  • Support for many Firefox extensions
  • Support for a growing number of Pale Moon exclusive extensions
  • Extensive and growing support for HTML5 and CSS3
  • Broad support for image formats: Supports WebP and JPEG-XR
  • Many customization and configuration options
