What Others Think

This is actually not right. It's only a coincedence with firefox if that's the case. Usually signal 1 HUP is the shortname for hang up which was initially used to re-read configurations without closing the program which is also the main use. If you want to close programs you need to use signal 15 (TERM) or more aggresive 9 (KILL).
