About Firefox Developer Edition
Firefox Developer Edition is a separate Firefox build for people who build websites. It is a pre-release version, so new web platform features and changes to the built-in developer tools arrive here before they reach the regular Firefox release.
Mozilla offers installers for Windows (64-bit, 32-bit and ARM64, with MSI packages for managed deployment), macOS and Linux (64-bit and ARM64). It no longer runs on Windows 8.1 and older or macOS 10.14 and older; Mozilla points users of those systems to Firefox ESR instead.
