On celebration of 10th Anniversary, Firefox has launched a browser just for the Developers. The Firefox Developer Edition.

From Mozilla blog…

One of the biggest pain points for developers is having to use numerous siloed development environments in order to create engaging content or for targeting different app stores. For these reasons, developers often end up having to bounce between different platforms and browsers, which decreases productivity and causes frustration.
Firefox Developer Edition solves this problem by creating a focal point to streamline your development workflow. It’s a stable developer browser which is not only a powerful authoring tool but also robust enough for everyday browsing. It also adds new features that simplify the process of building for the entire Web, whether targeting mobile or desktop across many different platforms.

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. You can inspect and debug apps across any browser. Some of these features were available to developer previously, now Firefox added some new powerful features for developers.
