Because that fits the pattern which is used e.g. in theme options for it. (I was literally comparing the markup to that line by line to spot differences.) However, there the only option is to pick an image, so feel free to revert that. Didn't realize that there could be files chosen here that are not image when I changed it.

Yes, as I mentioned before, it's a FF-only bug.
Elements containing responsive images using the Marcotte technique (max-width: 100; height: auto;) must not be a fieldset in FF for the responsive image CSS to work. It's got something to do with how fieldsets in FF currently handle overflow. I guess it actually kind of makes sense because fieldsets are not really supposed to contain images? Then again, fieldsets and legends are a pain in the ass anyway.
