Safari 11 - High Sierra 10.13. - Bing search engine - I have my Top Sites preferences set for "Shows 12 Sites". When I delete one of the 12 Safari automatically adds another. It is adding sites such as Yahoo and Trip Advisor although I DO NOT have Yahoo or Trip Advisor in any of my Bookmarks. Is this something Bing is doing? Is bing "selecting" sites for me? How can I stop it or set Safari to replace a Top Site I delete with, say, the next one in line in my Bookmarks?
