Macbook Pro -Safari, preferences, general, new window opens with - Favorites. -File, new window. I see Favorites, right click on the google icon, click on edit address. What I see here is https:/www.google.com/?client&channel=mac_bm. What is this? Even when I edit the address it will go back to this one. How is this extra part starting with the ? even added on in the first place?
