How do you stop Chrome filling in website addresses and also stop it from keeping a list of websites visited which show up in a dropdown list as soon as you start typing? It is most annoying especially when you think you are doing the right thing security wise with Internet banking, by typing the complete website name in the address bar. I know it's quicker etc but I would rather type it in myself. Thanks

You can do it in an incognito window, it won't save history, cookies, etc.
If you want that all the time, you can append the --incognito flag to your Chrome shortcut.
