If it is clear to others who can help you, then there is no need for you
to do anything; but if it is generally unclear, perhaps you could describe
again what you do, what you see, and what you want to see instead?

This seems to say that in FF you request /one.dds, and your nginx returns
a gzip-compressed version on the file one.dds. (And nginx compresses it
afresh on each request.)

*This* seems to say that in FF you request /one.dds, and your nginx
returns the contents of the pre-compressed file one.dds.gz.
I suspect that I am misunderstanding something.

And *this* bit, I'm not sure what it is intended to mean. In Safari you

What request do you make in Safari?
What response (http headers) do you get to that request?
What response do you want to get instead?
If you know that an Apache returns the response that you want, then
showing that output might answer the third question.
Alternatively, if Apache or nginx change their response based on the
User-Agent, you can try using "curl" to make the requests, using varying

Not yet; I don't know what the problem is.
Good luck with it,
