Why doesn't styling radio and checkbox via :after and :before pseudo-elements work in Firefox?

Question

css

There was stylization of checkboxes and radio through pseudo-elements. Here is an example checkbox: jsfiddle.net/rzqs55eb/1 . In chrome it works with a bang, and for some reason firefox does not show pseudo-elements for input elements at all.
CHADNT?

Answer 1

Well, in general, as far as I remember, input cannot contain :before and :after in principle, because it is not a "container" element.
Most likely, you have previously manipulated labels.
