Indeed, I'm really glad there is at least one popular browser not affected by this.

This is one of the many examples where a privacy-first approach pays off not just in terms of privacy but also in terms of security. In Germany we use the term "Datensparsamkeit" for this principle. Not sure if there is a well-established english term in the international community.

So why do other browers fill in these fields automatically? Why don't they wait until asked by the user? Because it is more "convenient" for the user? Moreover who benefits from that? Not the users, not the browser vendors, but all those websites with overly long registration forms. These confront their visitors with lots of irrelevant fields (birthday, gender, etc.) just for the sake of collecting data. Nobody would fill all that in voluntarily, but I guess more people will do so (perhaps accidentally) if their browser fills that in by default.
