Firefox Developer Edition replaces the Aurora channel in the Firefox Release Process. Like Aurora, 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.
A separate profileFirefox 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.
Experimental developer toolsWe'll include experimental tools that aren't yet ready to ride the trains to release.
For example, the Developer Edition includes the Valence add-on, which enables you to connect the Firefox developer tools to other browsers such as Chrome on Android and Safari on iOS
Set up for web developersWe've set default preference values tailored for web developers. For example, chrome and remote debugging are enabled by default.
- The only browser made just for developers, Firefox Developer
Edition was created with your workflow in mind. Build, test, scale and
more all from one place, for the first time ever.
