The app is primarily a reference application for the development of the XUL platform it builds upon, and additionally a potential replacement for Firefox.
Basilisk is a 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 best to provide an as stable and secure browser as possible with every official release of Basilisk Browser 64-bit for PC".
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.
Features and Highlights
- Support for all NPAPI plugins (Unity, Silverlight, 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.
Important differences with Mozilla Firefox:
- Uses Goanna as a layout and rendering engine. Goanna behaves slightly differently than Gecko in certain respects and may result in different display of web pages. e.g.: Goanna renders gradients in a more accurate color space (non-premultiplied).
- Builds on UXP, XUL platform in development. As such XUL is alive and well in this internet browser and will not be deprecated.
- Has some long-standing known issues with the Mozilla code-base fixed (e.g. CVE-2009-1232).
- It does not use Rust or the Photon user interface. You can expect a familiar interface as-carried by Firefox between v29 and v56.
- It does not use Electrolysis (e10s, multi-process browsing).
- It does not require a walled-garden extension signing.
