The Pale Moon browser - Your browser, Your way!
Pale Moon is an Open Source, Firefox-based web browser available for Microsoft Windows, Android and Linux (with other operating systems in development), 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 its own, independently developed source with carefully selected features and optimizations to maximize the browser's speed*, stability and user experience, while maintaining compatibility with thousands of Firefox extensions many have come to love and rely on.

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

With the current generation of Gecko-based browsers, there are 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 and more freedom in customization, to name a few things.

* 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".
