Basilisk: Everything You Need to Know

If you’re looking for a browser that combines the speed and privacy of Firefox with the customization of Chrome, Basilisk might be just what you need. But before downloading this open-source browser, it’s important to make sure your computer meets the system requirements.

What is Basil?

It is a free and open-source XUL-based web browser with a Firefox-style interface and operation. It is based on the Goanna layout and rendering engine (fork of Gecko) and is based on the Unified XUL Platform (UXP), which in turn is a fork of the Mozilla symbol base without Servo or Rust. It is a modern and comprehensive web browser. It aims to preserve the useful technologies that Firefox removed from its sibling. The browser is essentially a reference application for developing the XUL platform on which it is based, as well as a potential alternative to Firefox.

Why Choose Basilisk Browser?

There are several reasons why you should choose Basilisk Browser over other browsers. First, it offers better privacy and security features than many other browsers on the market. It includes features like tracking and ad blocking, as well as support for advanced security protocols like HTTPS.

Second, the browser is highly customizable. It allows users to change the appearance, behavior, and functionality of the browser using a wide range of add-ons and themes. This means you can customize the browser to suit your specific needs and preferences.

Finally, the browser is fast and lightweight. It’s designed to use fewer system resources than other browsers, meaning it runs smoothly even on older or less powerful computers.

Basilisk Browser is a development program. This means it should be considered more or less “beta” at all times; it may contain errors and is provided as-is, with potential flaws. Like any other free software community project, it comes without any guarantees or promises for any particular use. Of course, we will do our best to provide as stable and secure a browser as possible with each official release.

It should be noted that due to the focus on platform development, the browser itself (application icon) will be released and maintained primarily as-is, with few changes or developments to the user interface or front-end features of the browser. As the platform evolves, some Firefox features may be ignored; please do not expect this application to remain the same forever.

Important differences with Mozilla Firefox

It does not require the signing of an enclosed garden accessory.
Goanna is used as a planning and presentation engine.
It does not use electrolysis (e10s, multithreaded browsing).
Goanna behaves slightly differently from Gecko in some ways and may cause web pages to display differently.
It has long-known issues with patching the Mozilla codebase (e.g., CVE-2009-1232).
Goanna introduces hues in a more accurate color space (without pre-typing).
Based on the UXP and XUL platforms in development. Because XUL is alive and well in this web browser and will not be neglected.
It doesn’t use a Rust or Photon UI. You can expect a familiar interface as Firefox is loaded between versions 29 and 56.
