anytime I type www into the URL window firefox autopopulates youtube.com even though I have turned off auto suggestion. It shows up before the bookmarked links ! it always automatically checks the "Search suggestions ahead of address bar results" and will not let me uncheck it. I just dont want it to suggest anything and am okay typing the complete URL. How can I fix this issue? I am including snapshot of what the autosuggestion, settings and version info in the attached doc
