Uses the pre-Australis user interface ("Strata") as carried by Firefox during versions 4-28. Pale Moon has diverged from Firefox in a number of ways: It also continues to support some types of add-ons and plugins that are no longer supported by Firefox, including NPAPI plugins such as Adobe Flash Player, as well as legacy Firefox extensions. Pale Moon retains the highly customizable user interface of the Firefox version 4–28 era. The main differences are the user interface, add-on support, and running in single- process mode. Pale Moon originated as a fork of Firefox, but has subsequently diverged. There are official releases for Microsoft Windows, FreeBSD, macOS, and Linux, as well as contributed builds for various platforms.

Pale Moon, though, is optimised to take full advantage of modern processors, and this can give it a huge advantage over Firefox in some areas. In particular, Firefox is compiled with the most conservative of settings, to ensure that it''ll run on even ancient CPUs. And Pale Moon also drops support for Internet Explorer''s ActiveX and ActiveX scripting technology, which also offers a security benefit as it means the browser can''t be infected by malicious ActiveX controls. The crash report has also been stripped out, as it''s designed to work with server-side technology that isn''t available on. The program has been made more lightweight, for instance, by stripping out little-used components like the accessibility features, and the parental controls. Pale Moon is a customised version of Firefox, which has been carefully optimised for speed and efficiency.
