My thinking is the user should explicitly autofill each field. Yes, it involves more work, but it's really not much work to click on a field and pick the right autofill value.

I'm always concerned about using autofill because browsers eagerly fill any field they have data for.

This is how Firefox's autofill worked for me just now. Glad to see some more justification for getting off the Google train!

Firefox works that way and is in my view a much saner default. The best solution used to be in Opera long ago where they showed a little dropdown with the information that was going to be autofilled. You could accept it or deny it.

That sounds like a fantastic idea for an extention.

That would be super bad user experience. Simple and better alternative would be to show everything being auto filled in page in a browser dialog and confirm from user before actually auto filling it.
