These connections are in TIME_WAIT, indicating that the connection has been closed by your host but are kept alive by the kernel for the duration of the TIME_WAIT interval to be properly handle any TCP still in-flight somewhere, see [1] for more details. The fact that the connections have no associated program is because the TIME_WAIT state is handled by the kernel, and from the application point of view, they do not exist anymore. You can see that the connections were to TCP/80 and TCP/443, so very likely caused by Firefox connecting to HTTP/HTTPS servers before you closed it. You'll be fine.
