datetime-local field type is not working on Firefox 57
Input type datetime-local is not working on Firefox 57.
Modernizr.js says TRUE in command bellow, so, yes, they have datetime-local support:
Modernizr.inputtypes['datetime-local']
In about:options, datetime support is enabled.
In this site, datetime-local is enabled and working on Firefox 57: https://caniuse.com/#search=datetime-local
BUT, the datetime-local fields are not working at all as we can see here: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/datetime-local

You're correct that Firefox doesn't currently support datetime inputs - only <input type="date"> is supported. You can subscribe to this bug for updates: https://bugzilla.mozilla.org/show_bug.cgi?id=1283388 .
