I am trying to create a simple Chrome Extension, and want to connect it to a realtime database. I tried connecting it to Firebase, but I simply can not get it working.

I dont plan on storing any sensitive data. So far I have created the standard Chrome extension files, popup.html, popup.js, background.js, manifest.json.

I do not want to store the data locally, since all users should be able to see the stored data.

Any ideas on how to connect a chrome extension to a realtime database? Firebase?
