The Pale Moon Project - Custom-built and optimized Firefox-based browser for Windows

Welcome to the Pale Moon project homepage

Pale Moon is an Open Source, Firefox-based web browser for Microsoft Windows, focusing on efficiency and ease of use. Make sure to get the most out of your browser!

Pale Moon offers you a browsing experience in a browser completely built from source with carefully selected features and optimizations to maximize the browser's speed*, stability and user experience, while maintaining compatibility with the thousands of Firefox extensions you have come to love and rely on.

This browser, even though close to Firefox in the way it works, offers a different set of features than its sibling. A few carefully selected features have been disabled that are not in high demand, and that do not interfere with the way web pages are displayed or function; all to maximize the efficiency of the browser. Please see the page with technical details to learn exactly what the browser supports, and what it doesn't support. For example, if you need accessibility features or parental controls, then please visit the Firefox homepage and get the official, non-optimized version of the browser.

With the current generation of Gecko-based browsers, there are a few other differences between Pale Moon and Firefox that are more obvious and not just "under the hood": contrary to what Mozilla has done with their redesign of the user interface, Pale Moon will continue to provide a familiar set of controls and visual feedback similar to previous versions, including grouped navigation buttons of a decent size, a bookmarks toolbar that is enabled by default, tabs next to page content by default (easily switchable) and not in the least a functional status bar, to name a few things.

To download the current version** of the Pale Moon browser, please click below for the web-installer, which will check your system's capabilities to ensure the browser will work on your processor and operating system, and allow a quick choice of browser architecture, or download the installer of your choice by going to the appropriate download page from the menu at the top of this page!

* Please note that current, popular "benchmarks" are extremely limited in what they test and the way they test "browser speed". Pale Moon does not aim to have an "as high as possible benchmark score", but instead focuses heavily on overall browser smoothness, CPU usage, efficient networking and program-wide optimizations not related to a certain (limited) subset of functions. Benchmarks, by definition, do not provide a real world browsing scenario, and should not be relied on to determine "which browser is faster or better".

** For your convenience, Pale Moon only releases versions based on select and relevant version updates of the Firefox code, and will be released on a different release schedule than Firefox because of individual development, building and testing. If you need to run the very latest version of Mozilla Firefox code at all times (on the "bleeding edge") or prefer the latest features incorporated in Firefox development, then this browser may not be the best choice for you.
