Mozilla grandly launched the Firefox Developer Edition browser, specially created to meet the needs of developers. This version of the browser includes all Mozilla developer tools (previously only available as add-ons) and features a brand new dark UI.
Developer Edition replaces the Aurora channel on Firefox desktop version and includes two new features: Firefox Hello (a tool that makes calls and video chats directly from the browser) and the Forgot button (allowing users to clear the past 5 Cookies, history, tabs and windows that open within minutes, 2 hours or 24 hours).
Developer Edition also includes a range of other tools such as responsive design patterns, page inspectors, web consoles, JavaScript debuggers, network monitors, style editors, and web audio editors. This new release is part of Mozilla's efforts to make Firefox more useful to developers.
Just a few days ago, Mozilla celebrated Firefox's tenth anniversary. In 2004, the emergence of Firefox broke the Internet Explorer monopoly that Microsoft has established over the years and opened a new chapter in the "browser war".
As part of the celebration, Mozilla has launched a new Polaris privacy initiative, and a more compelling: Firefox Developer Edition browser.
As its name suggests, the developer version is designed entirely around the needs of the developer. No more or less, just right.
In the video below, Firefox Developer Tools Director Dave Camp introduces the new Firefox Developer Edition and briefly introduces new features and changes to the browser:
Camp stressed that the developer version is crucial to Mozilla, explaining that due to its focus on mainstream users, Mozilla sometimes had to "sacrifice the developer experience to improve Firefox's user experience." However, Mozilla promises to change that with the developer version.
Mozilla also explains why now is the best time to launch a browser designed for developers:
"Ten years ago, we built Firefox for early adopters and developers, giving them more choice and control. Firefox integrates Web APIs and add-ons to enable people to make the most of the web. Now, we will The entire browser serves as an exclusive area for developers, allowing us to put the features that are most relevant to them in the center. Having a dedicated developer browser means we can customize the browsing experience based on the developers’ daily work.”
News and Changes
The new developer version contains all Mozilla developer tools originally only provided as add-ons, such as the Firefox tool adapter (new name "Valence"), which provides more features for the WebIDE. This allows you to connect to Chrome for Android or Safari for iOS and modify web content, emulating Firefox environment.
On the other hand, WebIDE was launched in Firefox 33 as a beta feature (disabled by default) and is now officially included in the Developer Edition. It allows you to use the integrated editor to process Firefox OS applications in emulators, Firefox OS devices, or through Firefox for Android.
Automatic completion functions, pop-ups detailing function parameters and list verification are some new clever tricks included. You can also pause the application and check elements with the built-in debugger.
More strikingly, Firefox Developer Edition comes with a brand new dark UI, including square tabs like the older versions before Firefox 29 Australia. However, if you are not used to dark themes, you can change the interface theme through the Custom command. This seems like an interesting approach, with many details added.
Firefox Developer Edition replaces the Aurora channel on Firefox desktop Edition, but the Android version of Aurora will remain the same. For those unfamiliar, Firefox Aurora is located between Nightly and Beta development channels, and development starts at Nightly, it is the freshest Firefox code built daily with the latest features.
Nightly is followed by Aurora, which contains experimental features, then beta, and finally can be used in the stable version. You can find more detailed documentation on Firefox release management on the Mozilla Wiki.
The two latest features of Firefox have also been packaged into the Firefox Developer Edition and then released to the stable version of Firefox. The first is Firefox Hello, a WebRTC-based tool that can directly call and video chat with others from the browser without any plug-ins or add-ons.
The second convenient tool is the "Forgot" button. As the name implies, it allows you to "forget" cookies, history, tabs and windows that have been opened in the past 5 minutes, the past 2 hours or 24 hours.
Other tools
The Developer Edition also contains many other small tools:
- Responsive design pattern shows you how your website or application looks on different screen sizes without manually resizing your browser.
- Page Inspector allows you to check the HTML and CSS of any web page and easily modify its structure or layout.
- The web console displays recorded information associated with the web page and allows you to interact with it using JavaScript.
- The JavaScript debugger allows you to check or modify the JavaScript code state to make it easier to find errors.
- The network monitor displays the network requests issued by the browser, the time it takes for each request, and associates technical details with each request.
- Style Editor allows you to view and edit CSS styles associated with web pages, create new styles, and apply existing CSS stylesheets to any page.
- Web Audio Editor allows you to check and interact with Web Audio APIs in real time to ensure that all audio nodes are connected in the way they are expected.
For a list of all changes included in Firefox Developer Edition, you can view the details in Mozilla's release notes.
Evolution or revolution?
It is definitely an interesting way to see Mozilla move in "something new" direction. Although traditional Firefox browsers are mainly considered to be browsers for ordinary Internet users, developers have not taken full advantage of their potential.
With the Developer Edition, Mozilla plans to change this, which seems to be a good start to the effort. However, we have to wait and see how it will evolve in future releases and how it will affect developers.
