Pale Moon is an open source web browser based on Firefox that’s optimized for performance. It focuses on efficiency and ease of use, by leaving out unnecessary features and making optimizations, while maintaining compatibility with Firefox extensions and themes.

Features:

• Optimized for modern processors
• Firefox sourced: As safe as Mozilla’s flagship browser
• Supported by a friendly, active community of users
• Familiar, efficient, fully customizable interface (no Australis!)
• Smooth and speedy page drawing and script processing
• Increased stability: experience fewer browser crashes
• Support for Firefox extensions (add-ons) and themes
• Uses slightly less memory because of disabled optional code
• Support for SVG, Canvas and downloadable fonts
• Extensive support for HTML5, CSS3 and WebGL
• More customization and configuration options than Firefox
• Able to use existing Firefox profiles with the migration tool

This browser, even though close to Firefox in the way it works, offers a different set of features than its sibling. For example, if you need accessibility features or integration of Windows’ parental controls, then Pale Moon may not be a good browser choice for you.
