Firefox does not even have a default provider. It is not like the chatbot panel itself can even exist without a user actively choosing a provider and potentially having to log in. The default is to have a selection menu, which then basically loads the interface of the llm provider themselves. So when they introduced it I remember been prompted to select a provider or close it.

Similarly with their separate summarisation etc features I was prompted whether I wanted a local model, online model (I think), or not at all. It did not download 4gb of data without consent.

We can keep complaining about details forever but it is like missing the forest completely.

If you accidentally skipped it, go to Preferences -> AI Controls -> toggle on Block AI Enhancements, it disables everything.
