Firefox Developer Edition is a version of the Firefox browser optimized for web developers, offering advanced tools to modify, debug, and test web applications. It is separate from the regular, beta, and nightly Firefox versions and includes an independent profile, meaning it does not interfere with the data or settings of other Firefox installations. This is ideal for developers who need to test new features without affecting their normal workflow.
