FIY: quicksuggest aka "Firefox Suggests"

• browser.urlbar.quicksuggest.enabled controls wether the UI is shown or not (screenshot to follow). I think it works as a master switch for the whole feature but I haven't done any in depth testing.
• the above pref is also controlled by browser.urlbar.quicksuggest.scenario which can be set to online, offline or history, and which enables the quicksuggest experiment (I call it experiment cause that's what firefox calls it in its source code). even if I set browser.urlbar.quicksuggest.enabled to false with a .cfg file (both defaultPref and pref) that value would be changed to true based on the scenario.
• couldn't bother doing any super in depth testing but after a few fresh installs with different .cfg files I found that the only way to prevent that experiment from being enabled was to set the scenario to an empty string using pref (otherwise overwrote, but it doesn't matter for user.js files and I was just being precise). so browser.urlbar.quicksuggest.scenario = "", which guarantees that browser.urlbar.quicksuggest.enabled = false.
• browser.urlbar.suggest.quicksuggest and browser.urlbar.suggest.quicksuggest.sponsored control the checkboxes in the UI (again screenshot to follow)
• browser.urlbar.groupLabels.enabled didn't do anything for me, although I've read online a few times that it is used to control firefox suggests. no idea.

finally the screenshot (Settings > Privacy & Security > Address Bar) :

when the experiment is enabled "Address Bar" name changes to "Address Bar - Firefox Suggests".
