We already use .suffix, see https://searchfox.org/mozilla-central/rev/c3fef66a5b211ea8038c1c132706d02db408093a/browser/base/content/urlbarBindings.xml#1048-1055 . I think using prefix can be a follow-up bug, that doesn't seem super valuable to me (in fact, I would prefer to get rid of the alternate stuff as it's currently needlessly being mixed in with other bits of URL fixup in nsDefaultURIFixup, but that's a separate discussion).

I'll remove shift support here because it affects the pref name, and adding a pref and then renaming it immediately seems stupid.
