Pale Moon is an open-source web browser with an emphasis on customizability; its motto is "Your browser, Your way". There are official releases for Microsoft Windows and Linux, an unofficial build for macOS, and contributed builds for various platforms.
Pale Moon is a fork of Firefox. The project was forked when Firefox included an extensive range of customization and plugin capabilities from the version 4–28 era, that were planned to be removed in the near future, and which were actually removed in Firefox version 57 "Quantum". These included the entire XUL, XPCOM and Jetpack layers, which allowed full low-level customization of the browser and access to its full internal state while running, and the NPAPI plugin system. Pale Moon also rolled back the changes to the user interface which had already taken place, known as Australis, and declined to adopt the "one process per tab" model which Firefox was planning to roll out at a later stage. Firefox no longer contains these features which remain in Pale Moon, and as a result, the functionality which they enabled is often impossible in current versions of Firefox. As one intended result, the add-ons, plugins and themes, and user interface, which worked with earlier versions of Firefox continue to work with Pale Moon.
Pale Moon does not aim to converge back to Firefox. It aims to "steadily diverge" by retaining these features, while selectively adding security and new functionality enhancements as appropriate.
Pale Moon has diverged from Firefox in a number of ways:
Pale Moon's source code is released under the Mozilla Public License 2.0 except for parts relating to branding. To ensure quality, redistribution of officially branded Pale Moon binaries is only permissible under specific circumstances. The name and logo are trademarked by the project founder and cannot be used without his prior permission.
M.C. Straver is the project founder and lead developer. Straver's first official release of Pale Moon, in 2009, was a rebuild of Firefox 3.5.2 with tweaked compiler settings. Eventually the scope of the project grew, and version 24 became a true fork of Firefox 24 ESR. Starting with version 25, Pale Moon uses a completely independent versioning scheme.
In 2017, Straver began the Unified XUL Platform (UXP) project. UXP is a fork of Firefox 52 ESR with significant modifications to become a platform for creating any number of XUL-based applications, including a future version of Pale Moon. To demonstrate and refine UXP, Straver uses it to create a new browser, Basilisk.
Pale Moon for Android was a distinct development effort that is no longer maintained. First released in 2014, Straver announced the following year that it would likely be abandoned due to lack of community involvement. The final release was 25.9.6.
FossaMail is an email client created by Straver. It is a fork of Mozilla Thunderbird using the layout engine of Pale Moon. Straver ended official support of it in 2017, though he still maintains it for his own personal use and shares these updates via FTP.
Straver has downplayed the role of benchmark tests, stating that they "can't be used to draw hard (or regularly even any) conclusions. Plain and simple: they are an indication, nothing more. They serve well if you compare closely related siblings (e.g. Firefox and Iceweasel) or different builds of the exact same browser, to get a relative performance difference between the two on the limited subset of what is actually tested, but that's about as far as it goes."
