How do I make Firefox interpret my location as a non-FQDN subdomain on my local network?

Question

How do I make Firefox interpret my location as a non-qualified domain name properly when I type in a non-FQDN without dots?

For example, if I type "foo/home", I want to go to "http://foo/home", not to "https://duckduckgo.com/?t=ffab&q=foo%2Fhome&ia=web". But I can't find any such setting.

In about:config, set browser.fixup.dns_first_for_single_words to true.
