Firefox Developer Edition Overview

Firefox Developer Edition is an Open Source web browser available for Windows and macOS and Linux from Mozilla. The Firefox Developer Edition offline installer is a complete standalone setup file — every rendering engine component, extension framework, and security module is packed into a single download that installs without any internet connection. Unlike a web installer or stub downloader that pulls files during setup, the Firefox Developer Edition standalone setup works completely offline once downloaded. The Firefox Developer Edition standalone installer also makes it easy to keep an archived copy for future reinstalls or rollback scenarios. Download the Firefox Developer Edition full setup from the official Mozilla page and get a clean, trusted installation with no bundled adware.
