DevTools Extension Examples
This repository is a collection of DevTools extension examples, demonstrating how to build add-ons for Firefox DevTools using the WebExtensions APIs.
Getting started
To install and run any of the add-ons in this repository, follow the instructions for temporary installation in Firefox.
This is the developer way of doing it, and is not the way users of your add-ons will use.
If you're new to the WebExtensions + DevTools world, we recommend you look at the add-ons in the following order. Each directory contains a README file with more information related to that add-on.
devtools-panel
Shows how to create a new panel in DevTools.
console
Demonstrates how to evaluate scripts in the inspected window (i.e. the content scope).
messaging
(Work in progress)
Demonstrates how to communicate among different scopes.
