Why does Firefox not respect the HOSTS file in Windows

You don't get it. I have DNS Client service disabled.
Ipconfig /displaydns does nothing.

Yes, but your browser is probably already caching
as necessary.

FF caches for 60 seconds by default and the
value can be custom-set. But suit yourself.
Personally I don't have any problems with my
browsers.

Actually, Firefox goes to the other extreme. If
you don't set Network.dns.disablePrefetch and
Network.dns.disablePrefetchFromHTTPS to false
then FF will make DNS calls to links in the
webpages you read, just in case you decide to
visit them! And it gets worse. If you don't set
Network.prefetch-next to false then FF will also
load page content that you *might* decide to
visit. It's sacrifing both efficiency and privacy
so that it can look zippy on your next hop.
