It is very easy to find all the passwords stored in Google chrome. You can read more about it here-
*hackingtuts.com/find-all-the-passwords-stored-in-google-chrome/
But will it be able to retrieve the username and passwords if i delete the browsing history and if i choose dont remember password for all the sites that i visit? ? ?
I guess they r stored anyway....even if option is not selected(AFAIK)
It is not exactly a bug. The tool (ChromePass) mentioned in that site is a Google Chrome password recovery tool. There are similar tools for FireFox, IE, many IMs etc. You can find them here:
