Pale Moon

Pale Moon is an open-source web browser with an emphasis on customization; its motto is "Your browser, Your way". There are official releases for Microsoft Windows, FreeBSD, macOS, and Linux, as well as contributed builds for various platforms. 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 Adobe Flash Player, as well as legacy Firefox extensions. Overview Pale Moon has diverged from Firefox in a number of ways: Uses the pre-Australis user interface ("Strata") as carried by Firefox during versions 4-28 Supports extensions built with XUL and XPCOM, which are no longer supported by Firefox Supports "Complete Themes", add-ons which can customize the entire UI of the browser. Firefox no longer supports this and retains limited options for UI customization. Supports NPAPI plugins indiscriminately, all of which are no longer supported by Firefox Replaces the Gecko browser engine with the Goanna fork Always runs in single-process mode, whereas Firefox became a multi-process program 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 Unified XUL Platform (UXP) Pale Moon is built upon the Unified XUL Platform (UXP), a cross-platform, multimedia application base with ancestry in Mozilla code. It includes the Goanna layout and rendering engine, a fork of Mozilla's Gecko engine. Moonchild Productions develops UXP alongside Pale Moon.
