Firefox Developer Edition is a version of Firefox that's tailored for web developers. Firefox Developer Edition replaces the Aurora channel in the Firefox Release Process. Like with Aurora edition, features will land in the Developer Edition every six weeks, after they have stabilized in Nightly builds.
By using the Developer Edition, you gain access to tools and platform features at least 12 weeks before they reach the main Firefox release channel.
Firefox Developer Edition uses a separate profile from other Firefox versions installed on your machine. This means you can easily run the Developer Edition alongside your release or Beta version of Firefox.
