That setting just adds a button on your page that if you click it, it will refresh the game. It is marked danger because it could be abused to spam F5 which is a questionable action. If you don't see this button, labeled "F5", a green circle on the page, then there is no problem. There even is no problem if you have it enabled, as long as you dont spam it.

Auto-login is a totally different problem. Make sure you have the third checkbox checked on the DMM login page
