Hotmail sign out

When I recently logout of a hotmailaccount (Firefox) and want to login to another I get back to the first. After logging out you come to a page were it says :

Sign-out isn't complete...

You signed out of these sites:
MSN Account Services

We couldn't sign you out of these sites:
Hotmail

When I clear recent history I can login to another account, but that's not really great (other open tabs). Is there a solution and if not is there an add-on for clear recent history so it's just one icon to click?

 

That should not happen in the first place, once you click sign out, you should be signed out of the hotmail server. Local cookies should not cause you to remain signed in. If this happens again closing and restarting the browser should clear it up.

 

Yes, I know, but that has the same effect as clear recent history and that's faster. I'm curious why this happens all of a sudden.

 

See this for the solution. If you do not want to remove all your cookies every time, just tell Firefox not to save your hotmail cookie in the first place.

 

Changing "Keep until: ask me every time" into "Keep until: I close firefox" did the trick. Thanks.
