Since recently, Firefox has a built-in interface for chat bots.
Whether that's good or bad is a different discussion. Anyway this feature exists now and people might use it. So it makes sense to know what we are dealing with.
Does integration of chat bots in Firefox respect my privacy? Since I can chat with LLMs without needing a login or key, is my data anonymised?
I guess that's not the case, but maybe somebody knows more.
