This isn't robust. It will kill any process with "firefox" anywhere in its
command line, which isn't limited to processes which are actually running
the firefox web browser.

This line excludes one such process, but there may be others.
A more robust approach would be to check for the string in the command
name (i.e. argv[0]) rather than the complete command-line, by using e.g.
"ps ... -o pid,comm":
lines = os.popen('ps axheo pid,comm').readlines()
lines = [line.strip().split(' ', 1) for line in lines]
lines = [(int(pid), cmd) for pid, cmd in lines if 'firefox' in cmd]
Better still would be to check that "firefox" is a complete word, not part
of one, e.g. with the regular expression r"\bfirefox\b". This would match
"firefox", "/usr/bin/firefox", "firefox-bin", etc, but not e.g.
"kill_firefox", e.g.:
lines = [(int(pid), cmd) for pid, cmd in lines if re.search(r'\bfirefox\b',
cmd)]
That's about as good as you can get without using non-portable mechanisms
such as /proc/*/exe.
