Firefox Developer
Edition

Firefox Developer Edition (was Aurora) is the rapid-fire release channel for the next iteration of the Firefox Web browser. The Developer channel is where users can test the latest features and innovations. Users can expect an increase in polish from the raw, cutting edge features in the nightly builds. These releases may not be as stable as beta or final releases.

With Firefox Developer Edition:

• Experience the newest innovations in an unstable environment that's not for the faint of heart
• Provide feedback on features and performance to help determine what makes the final release

New

• For users with the unified search bar, search suggestions will appear ahead of browsing history by default. This can be changed in Settings on Windows and in Preferences on Linux and macOS.
• Added new settings in about:preferences that allow you to stop intrusive websites from asking you to receive notifications or access advanced device features such as camera and geolocation, while still allowing websites you trust to use these features
• Added locale: Interlingua (ia)

Changed

• Changed the location of Firefox Health Report from about:healthreport to about:telemetry
