Firefox Developer Edition
The browser made for developers
All the latest developer tools in beta, plus experimental features like the Multi-line Console Editor and WebSocket Inspector.
A separate profile and path so you can easily run it alongside Release or Beta Firefox.
Preferences tailored for web developers: Browser and remote debugging are enabled by default, as are the dark theme and developer toolbar button.
