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.
