Question

Using -webkit-object-fit in stylesheet in Chrome generates "unknown property name".

This extension is now supported without prefixes in all major browsers except Internet Explorer and Edge (although it is flagged as Under Consideration with medium priority in Edge, so it is likely to be supported there in the future).

Original (outdated) answer

This particular extension appears to be an Opera-backed project, as it has not garnered support from any other browsers.
