The quote in header Access-Control-Allow-Methods: "POST, GET, OPTIONS, PUT, PATCH, DELETE" can make it imcompatible with Firefox , delete the quote to fix the bug
If the response header is "POST, GET, OPTIONS, PUT, PATCH, DELETE" literally , Firefox would take "POST as an allowed method instead of the actuall POST.
I've test it on my cloud , when the " is gone , my angular program would work perfectly well.
