This is of course a great utility for Hotmail users and is more secure among such tools because neither your username nor password is needed. It works only after you log on at the Hotmail website. As long as you stay log on, this extension still works.
To use this tool, left click at the icon on the status-bar to reset counter and open Hotmail website. Right click at the icon on the status-bar to open popup menu to change options and middle click at the icon on the status-bar to check email now.
