Firefox Developer Tools

These are the tools provided by Firefox for developers to inspect Web code.

We abide by our code of conduct, and expect all contributors to do the same.

Documentation

• End user guides.
• Developers documentation - here’s an HTML version of these documents as well.
• Not strictly a roadmap, but these are some of our 2017 goals.

News and demos

We publish news and updates to two blogs:

• Nightly for features newly added to Firefox Nightly. This is the place to request feedback from early adopters!
• Hacks when features reach more stable versions of Firefox.

You’re more than encouraged to talk, write articles, or make demos about the tools. Let us know 🙂

Getting in touch

• Bug reports or feature requests:
  • File bugs in Mozilla’s Bugzilla (please respect the etiquette)
  • or under each repository in devtools-html for code in GitHub.
  • Report vulnerabilities to security@mozilla.org. More info.
• List of open bugs. Might be interesting if you want to contribute.
• DevTools forum.
• Mailing list.
• Team weekly video call: Vidyo room DevTools, Tuesdays 9AM Pacific time. Meeting notes.
• Chat:
  • Join the Firefox DevTools Slack,
  • or IRC: #devtools channel on irc.mozilla.org.
• Twitter: @FirefoxDevTools.

Processes

Most changes will be done via either the “pick a bug and send a patch” or “send a PR” processes.

For substantial changes, we ask that a “request for comment” (RFC) document is provided first, so we can examine what the implications of a change will be. Here is how to follow the RFC process.
