About Firefox Developer Edition

Welcome to your new favorite browser. Get the latest features, fast performance, and the development tools you need to build for the open web. All the latest developer tools in beta, plus experimental features like the multi-line console editor and WebSocket inspector. A separate profile and path so you can easily run it alongside release or beta Firefox. Preferences tailored for web developers, browser and remote debugging are enabled by default, as are the dark theme and developer toolbar button. Firefox DevTools now grays out CSS declarations that don’t have an effect on the page. When you hover over the info icon, you’ll see a useful message about why the CSS is not being applied, including a hint about how to fix the problem. The new Firefox DevTools are powerful, flexible, and best of all, hackable. This includes a best-in-class JavaScript debugger, which can target multiple browsers and is built in React and Redux.

Basilisk

A XUL-based web browser demonstrating 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. Basilisk is primarily a reference application for the 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.
