Remote Protocol (CDP)
The Firefox remote protocol (CDP) is a low-level debugging interface you can use to inspect the state and control execution of documents running in web content, instrument the browser in interesting ways, simulate user interaction for automation purposes, and for subscribing to updates in the browser such as network- or console logs.
It complements the existing Firefox Developer Tools Remote Debugging Protocol (RDP) by implementing a subset of the Chrome DevTools Protocol (CDP).
To use Firefox remote protocol with Fission, CDP client authors should read the Required Preferences page.
