A XUL-based web-browser built on top of the Unified XUL Platform (UXP). This browser is a close twin to pre-Servo Firefox in how it operates.

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.
