Google's "Functions Framework" is designed to run and debug "Google Cloud Functions" locally, see link.
On the other hand, Firebase Functions docs only mention the emulator as a means to run/debug Firebase Functions locally, see link. I have not been able to find any mention online of Firebase Functions working in the Functions Framework.
However, in some ways it would appear that any Firebase Function is actually also at the same time a "Google Cloud Function". For example, whenever you create a new Firebase Function, it will appear in the list of Google Cloud Functions in the Google Cloud Functions Console.
Given that the Functions Framework is supposed to be a superior debugging solution to emulators, I would like to know if I can use it with Firebase Functions or not.
Any clarification on the difference (or lack thereof) between Firebase Functions and Google Cloud Functions would also be welcome.
