How do you cite a paper with multiple first authors?

To avoid ambiguity, when the in-text citations of multiple works with three or more authors shorten to the same form, write out as many names as needed to distinguish the references, and abbreviate the rest of the names to “et al.” in every citation. This guidance is the same as in the 6th edition.

Is there a consensus that co-first authors should be in alphabetical order and is the editor likely to point this out? No, “A” has no right to require alphabetical ordering.

How is being first author related to size of contribution?

It is often related to size of contribution. In particular, being first author is often related to making the greatest contribution. But disciplines vary substantially in the meaning of author order.

Where do you put relative contribution of authors?

An appropriate place to mention relative contribution of authors is in the author note in a paper. More generally, there are a lot of variants on the “co-first-author” scenario. In some cases, authors will note equal contribution or that author order was determined by a coin toss.

How to cite paper with two co-first authors?

For example, in some cases the first and second author will have contributed equally. It seems more sensible to say that both authors contributed equally than to say that they were both “first authors”, because at the end of the day, a reference has to have a canonical order to the authors.
