can't kill os.system process

[david brochu jr]

When I run the following code:

import os

file = "C:\\progra~1\\mozill~1\\firefox.exe www.google.com"
os.system(file)
# this will spawn Firefox and naviage to google.com

kill = "taskkill /f /im firefox.exe"
os.system(kill)
          #
this should kill Firefox instance that was just spawned



the script never gets to kill the insance of firefox. When I manually close
Firefox, my cmd window indicates that the taskkill command was unsuccessful,
which leads me to believe that after I open Firefox the system is not
getting any indication that the command finished executing, which would
result in Firefox not being killed. I also tried substituting "os.system"
with "os.popen" which did the same thing.

Anyone have an idea how I can kill the instance of Firefox?
