Basilisk
A XUL-based web-browser demonstrating the Unified XUL Platform (UXP).
Basilisk is a free and Open Source XUL-based web browser, featuring the well-known Firefox-style interface and operation. It is based on the Goanna layout and rendering engine (a fork of Gecko) and builds on the Unified XUL Platform (UXP), which in turn is a fork of the Mozilla code base without Servo or Rust.
Basilisk as an application is primarily a vessel for development of the XUL platform it builds upon, and additionally a potential replacement for Firefox to retain the use of Firefox Extensions.
The browser is created and maintained by the team behind
Pale Moon , and is a fully independent fork of the 
Mozilla Firefox code.
Basilisk is a modern, full-featured web browser. It aims to retain useful technologies that its sibling Firefox has removed.
Main features:
Full support for JavaScript's ECMAscript 6 standard for modern web browsing.
Support for all NPAPI plugins (Unity, Flash, Java, authentication plugins, etc.).
Support for XUL/Overlay Mozilla-style extensions.
Experimental support for WebExtensions (in gecko-target mode). Please note that some Mozilla-specific WebExtension APIs are not yet available.
Support for ALSA on Linux.
Support for WebAssembly (WASM).
Support for advanced Graphite font shaping features.
Support for modern web cryptography: up to TLS 1.3, modern ciphers, HSTS, etc.

Comments and Reviews
Said about Basilisk as an alternative
soulriser It's faster and more stable.
SeanDFroszt Basilisk is what Firefox always was and still should be before they ruined it by trying to either be Google or kiss Google's butt by trying to be like them with WebExtensions and no support for XUL or *real* customization. Highly recommended, along with Waterfox or Pale Moon, this makes the third of the REAL "Mozilla" triumvirate.
Pale Moon successor new ui and DRM support :D

A very welcome option/alternative considering the questionable direction Mozilla Firefox is currently heading. From the same developers of Pale Moon, which I've been using since XP days, we can be assured this is a long term project.
