Firefox Developer Edition
Browser built for developers with advanced DevTools
What is Firefox Developer Edition?
Firefox Developer Edition is a version of Firefox specifically configured for web development. It runs on a separate profile from regular Firefox, includes experimental features before they hit stable, and comes with a dark theme and tools enabled by default. The DevTools are comprehensive: a powerful CSS Grid inspector, Flexbox visualizer, accessibility inspector, and network monitor. The JavaScript debugger supports source maps, breakpoints in async code, and worker debugging. Firefox also has the best compatibility testing tools for web standards. For developers who value privacy and open standards, Firefox Developer Edition is an excellent choice. Mozilla's commitment to user privacy means no invasive tracking, and the strong support for web standards helps you build accessible, compatible websites.
