Developer Edition

The Firefox Developer Edition is a version of Firefox that's tailored for web developers. It includes:

  • the latest Firefox features: Firefox Developer Edition replaces the old Aurora channel.
    • Each new release includes features which have been stabilized via nightly builds. 
    • New features enter the Firefox Beta channel six weeks before being released
    • New features are stabilized for 12 weeks before appearing in the released version of Firefox.
  • a separate developer profile: this means you can easily run the Developer Edition alongside your release or Beta version of Firefox.
  • experimental developer tools: we'll include experimental tools that aren't yet ready for production.
  • preferences tailored for web developers: we've set default preference values tailored for web developers. For example, chrome and remote debugging are enabled by default in the Developer Edition.
  • a distinct theme: this includes quicker access to the developer tools.
