Unless something has changed that shouldn’t be an issue.

Can I use firebase in website hosting on your platform?

Yes, of course! Just add the Firebase SDK to your code, configure it and off you go! After all, Firebase is just a service somewhere else with a HTTP API. We don’t prevent your site from communicating with other services (except for a few social APIs that were being abused a lot), including Firebase.

Can you please explain or show us the exact error or issue you’re having?
