You can rid Google's URL suggestions when Googling by setting the preference to disable on the search bar but the cookies has to be enabled otherwise they keep coming back, but there is a way round this.
Simply bookmark this link Google or add it as a tab... you can now Google with Cookies disabled without the annoying URL search suggestions popping up as you type..
You can of course do it the hard way by typing >>http://www.google.com/webhp?complete=0<<< in the address bar and then save as a bookmark or tab.
We are simply adding webhp?complete=0 to the address bar.
