Program: Basilisk Web Browser
License: Free & Open Source
Description: 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.
Other: It has a Portable version.
Note: Basilisk is development software. This means that it should be considered more or less "beta" at all times; it may have some bugs and is provided as-is, with potential defects.
