Pale Moon originated as a fork of Firefox, but has subsequently diverged. The main differences are the user interface, add-on support, and running in single-process mode. Pale Moon retains the highly customizable user interface of the Firefox version 4–28 era. It also continues to support some types of add-ons and plugins that are no longer supported by Firefox, including NPAPI plugins such as Flash Player.
Pale Moon has diverged from Firefox in a number of ways:
- Always runs in single-process mode, whereas Firefox became a multi-process program.
- Replaces the Gecko browser engine with the Goanna fork
- Uses the pre-Australis Firefox user interface
- Continues add-on support for XUL, XPCOM, and NPAPI plugins, all of which are no longer supported in Firefox.
- Supports add-ons exclusive to Pale Moon, including dozens of themes. These include retention of "Complete Themes", themes which apply to the entire UI of the browser rather than affecting only a few elements, support for which was removed in Firefox.
- Defaults to a customizable start page in cooperation with start.me
- Defaults to DuckDuckGo as the search engine instead of Google or Yahoo!
- Uses the IP-API service instead of Google's for geolocation
Version 25.7.0 was the final release to actually support Windows XP. Version 27.9.4 was the final official release to support Windows Vista as well as the final unofficial release for Mac OS X 10.6 Snow Leopard.
The end of XP support was quickly followed by Pale Moon getting at least two forks of its own, both of which take the most recent Pale Moon code and recompile it for XP; New Moon by roytam1, and Mypal by Feodor2.
The Pale Moon developers have since forced Feodor2 to discontinue Mypal over a license technicality.
The final version for Snow Leopard is the foundation for the Arctic Fox web browser.
The official releases do not support older processors without the SSE2 instruction set. However, a contributed build for Linux was available that supported some older processors, but it has since been discontinued.
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.
In 2018, How-to Geek, remarked that the then current version of pale moon was based on 3 year old firefox codebase. As a result, it is harder for the developer to support new interface and security features. It was also noted that the development resisted new features only to make a major leap to them every few years and advised to stick to a continuously updated browser like Firefox.

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.[jargon] 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.
Since September 2021 preview (unstable) releases are no longer distributed. The publishing of source code has also been reverted to a cathedral-style of tarballs upon release of binaries, instead of a publicly-available repository.
Straver created a new browser, Basilisk, as a "reference application" for developing UXP. First released in 2017, Basilisk is a perpetual beta intended to refine the UXP codebase it is built from. Pale Moon and other applications are also built from this codebase.
Like Pale Moon, Basilisk is a fork of Firefox with substantial divergence. Basilisk has the user interface of the Firefox version 29–56 era (unlike Pale Moon, which has the Firefox 4–28 interface).
For add-ons, Basilisk has roughly similar support as Pale Moon for XUL/XPCOM extensions and NPAPI plugins, all of which are no longer supported in Firefox. Basilisk also had experimental support for current Firefox WebExtensions, but this was removed in February 2019.
There are Basilisk releases for Microsoft Windows and Linux. Basilisk for MacOS, codename "Serpent" is a unofficial and discontinued version of the Basilisk web browser. It is similar to the original Basilisk. It was released its final version on June 11, 2020, and discontinued support on March 10, 2021.
Basilisk is still in active development as of October 2021.
Released in August 2018, Pale Moon 28 was the first version built on UXP, thereby providing improved support for web standards and video.
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.
On 10 March 2021, all Apple Macintosh support was dropped due to lack of consistency from community developers for the Mac platform.
On 31 March 2021, Brian Smith released a fork for macOS called White Star.
Current (UXP) versions of Pale Moon score comparatively to other browsers in benchmarks, showing, for example, no significant difference on the Sunspider benchmark compared to Firefox Quantum.
Straver has remarked that the role of benchmark tests is questionable, 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." How-to geek has remarked that while the developer disagrees with the benchmarks, it isn't surprising that old codebase will be slower.
The questionable role of benchmarking was later confirmed by leading technology experts when, for example, Google announced it was retiring its Octane benchmark in 2017, and Mozilla indicating that they "believe these benchmarks are not representative of modern JS code" when introducing WarpBuilder in November 2020, admitting that their new technology "is currently slower than Ion on certain synthetic JS benchmarks such as Octane and Kraken".

Data breach incidentEdit
It was reported on 10 July 2019 that a data breach of the archive server holding previous binaries of the Pale Moon browser had occurred and malware inserted into the executables. This breach was discovered on the previous day. It is unknown when the breach first occurred. At first, it was estimated to have been as early as 27 December 2017, according to timestamps. After getting some more feedback from users, it is now estimated to have occurred somewhere between April and June 2019.

Pale Moon supports NPAPI plug-ins. Unlike Firefox, we will not be deprecating or removing support for these kinds of plug-ins. This means that you will be able to continue using your media, authentication, gaming, and other plug-ins in Pale Moon like Flash, Silverlight, bank-authenticators or networking plug-ins for specific purposes.
