What is the Difference Between the Regular and Developer Editions of Firefox?

The Firefox Developer Edition is a modified version of Firefox that is specifically designed for web developers. It also uses a separate profile from the regular version so that running them side-by-side is an option. That does mean that all your add-ons and settings will not be available in the Firefox Developer Edition, but you can use Firefox Sync to get your add-ons and settings synchronized on both versions.

All features in the Firefox Developer Edition will be available 12 weeks before they are available in the regular version of Firefox.

Some features built into the Firefox Developer Edition that the regular version does not have are:


The Web IDE allows you to develop, deploy, and debug web applications directly in a browser or on a Firefox device. It allows you to create a new Firefox OS application (which is just a web application) from a template or open the code for an existing application. From there you can edit the application files. Click it to launch the application on the simulator, and another click to debug it using the developer tools. You can watch a video on the Web IDE on YouTube here.


Formerly known as the Firefox Tools Adapter, Valence allows you to develop and debug an application for multiple browsers and devices by combining Firefox developer tools with other major browser engines. Valence also extends the capabilities of the excellent tools created for debugging Firefox OS and Firefox for Android in other major mobile browsers, including Chrome on Android and Safari on iOS. Today, these tools include Observer, Debugger and Console, and Style Editor. You can watch the Valence video on YouTube here.

Web Audio Editor

The Web Audio Editor lets you inspect and interact with Web Audio APIs in real-time to ensure that all audio nodes are connected in the way you expect.
