Firefox Developer Edition: A Developer's Perspective

Last week, Mozilla surprised many by announcing the release of nothing less than a new browser . Firefox replacement? Not at all, since it is actually a browser for developers. Designed by developers for developers, Firefox Developer Edition (it's starting to make a lot of “developer”) is finally available.

But what is he hiding? What is so different about Firefox Developer Edition compared to a regular Firefox? To answer these questions, I plunged my nose as a web developer right into it to answer the main question you are probably asking yourself: was it really useful?

Firefox Developer Edition A Developers Perspective

The environment

By default, Firefox Developer Edition comes with its own dark, blue / gray theme. In other words, Firefox Developer Edition is by default close to most current text editors which almost all offer a dark theme, less tiring on the eyes.

Via the customization menu that we know since the arrival of the Australis interface, it is possible to deactivate this theme to find that of a more classic Firefox.


The theme is good, but what really matters for a browser dedicated to developers are of course its features. And on that, Mozilla has gone all out.

For example, the WebIDE text editor is directly integrated with Firefox Developer Edition. Allowing you to manage several projects and test them live on other browsers, WebIDE has its advantages. But also its disadvantages: paradoxically, it does not seem to offer a dark theme.

At the same time, we can also count on the integration of Valence. Previously called Firefox Tools Adapter, this tool allows you to find Firefox development tools on other browsers like Chrome or Safari, which is particularly useful for resolving compatibility issues with familiar tools. the best.

With these two integrations, we of course find the good old tools used almost daily by developers, such as the adaptive view for example which allows you to simulate the screen size you want inside Firefox, the DOM inspector or of course the JavaScript console to name a few.

We mustn't lie to ourselves: most of the tools offered by Firefox Developer Edition were already there in Firefox. They are however more highlighted by default, with a well adapted theme and well placed buttons.

So, useful or not?

It is obvious but as much to say it clearly: Firefox Developer Edition is totally useless for those who do not develop. For others, however, and there are many, this new browser is worth it.

Especially since a particularly interesting aspect slips on the scales: Firefox Developer Edition actually replaces Firefox Aurora, a test version of the free browser. Firefox Developer Edition will therefore make it possible to obtain the most recent features more quickly without risking the instability of a Nightly: Firefox Developer Edition can be used without problems on a daily basis and it's pretty cool.

In short, Firefox Developer Edition is a nice surprise for developers. Personally, I think I will keep Firefox for classic use and only dedicate Firefox Developer Edition to development, but why not migrate completely afterwards.

In any case, if you are a developer, at least give it a chance by downloading it from this address !
