Pale Moon 15.0

Pale Moon is a custom-built and optimized Firefox-based browser for Windows operating systems with current, high performance processors. It looks identical to the standard Firefox browser and supports Firefox extensions, themes and identities.


  • Highly optimized for modern processors
  • 100% Firefox sourced: As safe as the browser that has seen years of development.
  • Uses slightly less memory because of disabled redundant and optional code
  • Significant speed increases for page drawing and script processing
  • Stability: experience fewer browser crashes.
  • Support for SVG and Canvas, and downloadable fonts including WOFF
  • Support for HTML5 and WebGL (v4+)
  • Support for Firefox extensions (add-ons), themes and personas
  • Support for OOPP (Out-of-process plugin execution)
  • Able to use existing Firefox bookmarks and settings with this migration tool

What's new in this version:

This is a new release based on the Gecko 15.0 code base with additional branch development. It incorporates many changes under the hood that go far beyond the scope of this document.

A few highlights, in addition to security fixes:

  • Performance improvements for the rendering engine
  • More HTML 5 implemented
  • Better handling of memory, resulting in smoother operation of the browser
  • More responsive user interface when the browser is busy
  • Prevention of memory leaks through add-ons
  • Better implementation of the Quickdial page
  • Localization of Pale Moon specific preferences and options (work in progress)
  • Reinstatement of the previous user interface, keeping it in line with version 12 (Firefox 15 has UI changes that makes the controls flat, monochrome and borderless, which isn't desired for Pale Moon)
  • The padlock has returned for secure pages! It can be found in front of the URL when you browse to a secure page, with optionally company information if supplied by the server

Some things new to the Firefox code base that are excluded or disabled by default:

  • Built-in PDF reader in javascript - use a standalone, dedicated reader
    (this is both a security and functionality consideration)
  • Additional advanced web development tools - the average user never needs these
  • Web apps on the desktop - Pale Moon is a browser, not a pseudo-OS
  • Windows Metro UI
