Debugging Modern Web Applications

The Firefox Dev Tools team is excited to share news about an upgrade to the debugger’s source map support that lets you inspect the code you actually wrote. Combined with the ongoing work to provide first-class JS framework support across all our devtools, these advances will boost productivity for web app developers working in frameworks like React, Angular, and Ember and with modern tools like Webpack, Babel, and PostCSS.
