debugger

A hackable debugger for modern times, built from the ground up using React and Redux. It is designed to be approachable, yet powerful. And it is engineered to be predictable, understandable, and testable.

Mozilla created this debugger for use in the Firefox Developer Tools. And we've purposely created this project in GitHub, using modern toolchains. We hope to not only create a great debugger that works with the Firefox and Chrome debugging protocols, but also develop a broader community that wants to create great tools for the web.

Quick Setup

Or take a look at our detailed getting started instructions.

First, get a recent version of Node.js to run the debugger.

curl -o- -L https://yarnpkg.com/install.sh | bash -s
git clone https://github.com/firefox-devtools/debugger.git

cd debugger
yarn
yarn start
# Go to http://localhost:8000

If you are having problems with setting breakpoints in the debugger, launch Firefox Nightly instead of clicking on Launch Firefox.
