I use the same login on several computers, mostly running Firefox, and the new messages function never seems to catch up. I can look at new messages on my work computer then mark them all as read, and when I get home all of those same messages are new on that computer. It used to recognize multiple location/same login and mark the message the same at all locations. What gives? Not a huge emergency in the grand scheme of things, but just curious as to if there is a fix or a setting I've missed.
