Close session — Close all open windows
Closes all open browser and handler windows.
If any open windows hold any form of “unsaved” data, the user will be queried whether to save that data or discard the “changes” or whether to cancel the closing operation.
In case the operation was cancelled, any following windows will remain open as well, independent of whether they contain “unsaved” data or not.
The order in which the windows are being closed depends on their activation history and is thus not necessarily the same as the order in which they appear in the window list.
