Mozilla Launches Firefox Developer Edition

For the past week we've been teased by Mozilla launching a new web browser for developers and today they've lifted the lid on Firefox Developer Edition.

Firefox Developer Edition is targeted for web developers and replaces Firefox's existing Aurora channel. Firefox Developer Edition is thus where new Firefox features will first land -- 12 weeks before they're found in stable Firefox -- and will also feature experimental developer tools, uses default preferences targeting web developers like better debugging support, uses a separate profile from existing Firefox installations, and has a distinct theme to easily differentiate the Firefox build.

More information on Firefox Developer Edition can be found at So at the end of the day it's not a whole new browser for developers but effectively is based on what was Firefox Aurora as their platform for developers / early adopters, still is using the Gecko layout engine, and its default settings are more catered to web developers. The current Firefox Developer Edition build is marked for v35.0a2.

Shown is a screenshot I just took of Firefox Developer Edition running on my Ubuntu 14.04 LTS system.

Update: There's now this Mozilla Hacks blog post with more details on Firefox Developer Edition.
