Back out bug 1426216 (show search suggestions above history in urlbar in some cases) and follow-ups on release. r=Mossop, a=ritu There are four bugs that need to be backed out: 1. https://hg.mozilla.org/releases/mozilla-release/rev/152720a4efe7 (bug 1432716) 2. https://hg.mozilla.org/releases/mozilla-release/rev/84a24eb373fa (bug 1432263) 3. https://hg.mozilla.org/releases/mozilla-release/rev/4d423fdc33dd (bug 1429974) 4. https://hg.mozilla.org/releases/mozilla-release/rev/440dbdb51f94 (bug 1426216) The original bug implementing the problematic feature (pref migration + UI) is 4, and the others are improvements to it.
