Adding affiliation at the proof stage I have a paper to which I am 3rd author from my previous postdoc, and recently I got another postdoc in another institution. Is it fair and ok to add the new affiliation now, at the proof stage?

Yes. You could insert a footnote saying that the research feeding into the paper was carried out and completed while you were affiliated with university -1 in their lab 'so and so'.

This way, everybody is happy, and you're transparent about your whereabouts.
