If you're using a Windows OS, navigate to Start > Control Panel or Start > Settings > Control Panel on some versions.  If you're in Category View, click Network and Internet Connections > Internet Options.  If you're in Classic View, just double click Internet Options.\n\nAt the top of the window that opens will be some tabs.  Click on the one that says "Content", then click "Auto Complete", then uncheck each box and clear forms and passwords, then okay your way out.  Hope this helps.  Good luck.
