Do Not Show Thumbnails when I open a new tab in Google Chrome

Taken from the Google Chrome Help Forum:

The only way I know to do this is to go into incognito mode. To do this hold down ctrl+shift+n and this will open a new window in incognito mode.

If you want to run in incognito mode all the time you can append --icognito to your shortcut. So it would look this: "...\Chrome\Application\chrome.exe" --incognito

Click the drop down arrow & click on the most visited & recently closed options (which would have been selected before). Now you'll have a new tab just like the one you get in an incognito window
