Mozilla has added and enabled a new option ‘Related Searches from the default search engine’ to ‘Location Bar’ in ‘Privacy’ of Options on Firefox 41 Nightly, with this, when you type a phrase or word, search suggestions appear at the bottom of the drop down in the location bar when you scroll.
Firefox almost displays the same search suggestions as Google does when you use it as default search engine (check the screenshots below).
Disabling Search suggestions in Firefox
If you don’t want them to appear, remove the check mark for ‘Relates Searches from default search engine’ in Privacy options or change about:config preference browser.urlbar.suggest.searches to ‘false’.
