You need to click either ‘Yes’ or ‘Not’, if not, you’ be nagged throughout and after the session with that message unless or until you set ‘browser.urlbar.userMadeSearchSuggestionsChoice‘ to ‘true‘.
If you click ‘Yes’, Search suggestions from Search engine will be fetched and shown in real-time when you type, and you can notice ‘Related searches from the default search engine‘ option in the location bar in Privacy enabled as a result of this.
If you click ‘NO’, the feature will be disabled and so the option in the location bar option as a result of this.
