To reproduce: - Open multiple instances of the Mozilla application - Open Task Manager (Ctrl-Alt-Delete) - Close one instance of Mozilla you see Result: After a small delay, all instances of Mozilla get closed. I would expect that only the one I got selected was closed.
If you're talking about the same binary, we don't have multiple instances (like IE does), they're all the same process space...
Reporter, there is only 1 instance of Mozilla in the Task Manager, whuihc is used for all windows together.

window != process Some apps, especially primitive like Notepad, open a separate process per document, because they can only deal w2ith 1 document (so, window) at the same time. Other apps can open multiple documents in multiple windows, for example most word processors. Other apps will try to assign each document to each own process on purpose, but that's normally to add the possibility that a single document can crash your app, without affecting the others. Or to hide that they've made errors and in the design, and they really can't handle 2 documents at once. The disadvantage is that it consumes much more memory, and the 2 apps needs to cooperate very closely together (the user will not even notice). Both Word and Internet Explorer are in that last category (separate process per window), but none of the other browsers do this (they're in the second). See bug 117222 for a discussion about on the side effects.
