Pale Moon is an open source web browser forked off from Firefox, focusing on efficiency and ease of use, by leaving out unnecessary features, making optimizations, and having a fully customizable user interface, while maintaining compatibility with many Firefox extensions as well as its own extensions and themes.
IMPORTANT: We will no longer be using SourceForge from this point forward and will provide updates through our own site: http://linux.palemoon.org/
Pale Moon provides a familiar set of controls and visual feedback similar to previous (pre-Australis) versions of Firefox, including grouped navigation buttons, a bookmarks toolbar that is enabled by default, tabs next to page content by default, and a functional status bar.
