Welcome to the Pale Moon for Linux wiki!
Pale Moon is an open source web browser forked off from Firefox, focusing on efficiency by leaving out unnecessary features and making optimizations to maximize the browser's speed, stability and user experience, while maintaining compatibility with many Firefox extensions and themes, in addition to having its own extensions.
Pale Moon will continue to provide a familiar set of controls and visual feedback similar to pre-Australis versions of Firefox, including grouped navigation buttons, a bookmarks toolbar that is enabled by default, tabs next to page content by default (easily switchable) and a functional status bar.
More information regarding the project is available on the Pale Moon project's home page.
This page on SourceForge is an endorsed third-party build for Linux. Binaries can be downloaded from here.
