Thanks for the comment, that worked with the option "Use a prediction service to help complete searches and URLs typed in the address bar."

Is there any way to disable search suggestions in the address bar? In other browsers, I normally have used the address bar to search for pages which I've already visited by entering keywords contained in the URL/page title; however, in Opera, most of the time it shows Google suggestions instead. I already added back the search box, so I don't see a need for the suggestions when I can just use the search box if I want suggestions. I tried added a dummy search engine to prevent this, but you can't use a custom search engine as the default???

I noticed that when I open multiple incognito windows, they all share the same cookies. Is it possible to have entirely separate incognito windows?
