Basilisk Web Browser

Free Download Basilisk Web Browser offline installer for Windows PC it is a free and Open Source XUL-based web browser, featuring the well-known Firefox-style interface and operation created by the developers of the Pale Moon browser.

Basilisk Web Browser 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 is primarily a reference application for development of the XUL platform it builds upon, and additionally a potential replacement for Firefox.

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. Like any other Free Software community project, it comes without any warranty or promise of fitness for any particular purpose. That being said: of course we will do our best to provide an as stable and secure browser as possible with every official release of Basilisk.

It should be noted that because of this focus on platform development, the browser itself (the application code) will be released and maintained mostly as-it-is, with very little change or development on the user interface or browser front-end features. As the platform develops, some Firefox-specific features may be dropped; please do not expect this application to remain the same, forever.
