  1. Run this in a browser console:
mimeService = Cc["@mozilla.org/mime;1"].getService(Ci.nsIMIMEService);
mimeService.getFromTypeAndExtension("application/x-asfgsdfgsdfgsdfgfds", ".something").primaryExtension

ER:

.something

AR:

Uncaught Exception { name: "NS_ERROR_NOT_INITIALIZED", message: "Component returned failure code: 0xc1f30001 (NS_ERROR_NOT_INITIALIZED) [nsIMIMEInfo.primaryExtension]", result: 3253927937, filename: "debugger eval code", }

Windows and Linux do set the primary extension.

Update: in addition to macOS, android also does not set the primary extension.
