Formerly known as Firefox Quantum, Firefox Developer Edition is a specialized web browser built especially for web developers. Some of these tools and features eventually do make their way into the main Mozilla Firefox web browser.
Stepping aside from the main development branch of Firefox, Firefox Developer offers a number of features that are currently not present in Firefox, namely beta features and tools for web development.
The look and feel of Firefox Developer Edition is slightly different from the main release, but it's nothing to get too excited about; it's mainly just the color scheme.
In terms of tools, Developer Edition provides a WebIDE, Browser Console, Responsive Design Mode, Eyedropper, Scratchpad (for JavaScript debugging) and Service Workers. These tools can be handle for testing web applications.
Like the main branch of Firefox, this version also includes the main development tools like the Inspector, Console, Debugger, Style Editor, Performance tab, Memory, Network, Storage and Accessibility.
