Cleaner/more portable solution with psutil (well, for Linux you have to drop the .exe part or use .startwith("firefox"):

import psutil,os
for pid in (process.pid for process in psutil.process_iter() if process.name()=="firefox.exe"):
    os.kill(pid)

that will kill all processes named firefox.exe

EDIT: os.kill(pid) is "overkill". process has a kill() method, so:

for process in (process for process in psutil.process_iter() if process.name()=="firefox.exe"):
    process.kill()
