MSN does not signout

I'm sending this issue/concern to find out how I could make k-meleon signout completely from MSN or Hotmail.com. If there is a missing plugin that need to be installed.

No but You need to camouflage as Firefox 2 get full services at Hotmail, Yahoo...
Else a temporary glitch of the site or UR PC.
Either use AutoSwitcher extension by disrupted (which I recommend to do) or menus Tools -> UserAgent -> Firefox. Privacy Bar -> User Agent & Right Click allows 2 change also.
