This is the repository for an experimental Firefox DevTools extension.
The extension provides web compatibility information about the currently selected element as a new sidebar panel in the inspector.
To run the extension locally, first clone the repository, and then run the following commands:
npm installnpm run dev
This will automatically start Firefox Nightly with the extension already installed. Visit any website, open the inspector, and look for the Compatibility tab in the sidebar.
Tests are located in extension/lib/test/ and can be run with the following command: npm run test.
