Thanks for this rule, I have added Disconnect and suspend to my list of essentials.
My browser is locked down tighter than a nuns crotch and with other stuff I do I'm pretty secure.
From what I can tell. Disconnect is a good one because it will Disconnect the session after a period of time for security and hence the active session being stopped it promotes security for number of reasons.
