Hi Andrea, I'm not sure what you need to be rolled back with "restore to default." You could open an issue at https://github.com/jscher2000/printable-print-doctor-extension/issues or send me a message at jscher2000@outlook.com with more details.

I definitely should add control over headers/footers. I have a different add-on (https://addons.mozilla.org/firefox/addon/save-to-pdf-now/) which has a more comprehensive panel, so it's certainly possible, I just didn't think to add it here, too.
