How does password autofill work?

I'm curious: when I choose to autofill a saved password, does Firefox copy and paste the password under the hood, i.e. does the password ever appear in my clipboard, or does Firefox emulate the keyboard to fill in the password? Or something else?

Thanks!

Basically, the browser looks for a fill-in box for user-id or password. If found, it calls the Password Manager. The manager will look for and fill in any data it has for that website. If you enter new, or change, the data the manager will ask if you want to save it. The clipboard is not used.

Note that the clipboard is used if you click the Copy button on the Lockwise (about:logins) page.
