Basilisk

Basilisk is a free and open-source XUL web browser featuring a well-known Firefox-like interface and operation. It is built on the Goanna layout and rendering engine (a fork of Gecko) and the Unified XUL Platform (UXP), which itself is a fork of Mozilla's codebase without Servo or Rust. Primarily, Basilisk serves as an application for developing the XUL platform it's based on, while also offering a potential alternative to Firefox for those seeking to retain the use of Firefox extensions. Basilisk is a modern, full-featured web browser designed to preserve useful technologies that its sibling Firefox has phased out. Key Features: Full support for modern web browsing standards, including the ECMAScript 6 standard for JavaScript. Support for all NPAPI plugins (Unity, Flash, Java, authentication plugins, etc.). Compatibility with XUL/overlay-style Mozilla extensions. Experimental support for WebExtensions (in Gecko compatibility mode). Note that some Mozilla-specific WebExtension APIs are not yet available. ALSA support on Linux. WebAssembly (WASM) support. Advanced Graphite font shaping capabilities. Modern web cryptography support: up to TLS 1.3, contemporary ciphers, HSTS, and more. Windows Requirements: Windows 7 or later. 1GB RAM (2GB or more recommended for heavy usage). A dedicated GPU is highly recommended. Linux Requirements: A reasonably modern Linux distribution. The browser may not perform well on older or LTS versions of Linux. Release builds are compiled on Ubuntu 18.04. 1GB RAM (2GB or more recommended for heavy usage). A dedicated GPU and hardware-accelerated video are strongly advised. GTK 2.24 or GTK 3.22+ (not GTK 4). GLIB 2.22 or later. Pango 1.14 or later.
