Firefox developer edition review

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 story of Firefox and Firebug are synonymous with the rise of the web. We fought the good fight and changed how developers inspect HTML and debug JS in the browser. Firebug ushered the Web 2.0 era. Today, the work pioneered by the Firebug community through the last 12 years lives on in Firefox Developer Tools.

Firefox Developer Edition integrates all the developer tools you'll need into one package. It is the only browser dedicated to developers. How do I switch between the Developer Edition and standard themes? Click the menu button, then +Customize and click Use Firefox Developer Edition theme to.

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.
