Please incorporate equivalent to mozmm available in Geckos


The mozmm is a proprietary/non-standard CSS length that enables Gecko users whose physical display density is matched to the environment’s logical display density to display web page objects at accurate physical sizes, something that standard CSS eradicated some years ago. Browser engines WebKit, Blink, Trident & Edge all strictly complied with the eradication directive. AFAIK, only KHTML enables display of physical sizes accurately by default, by having kept the classical meanings of pt, cm, in, etc.
