_ff-addon-snippet-NsiProcessNoPidPollution - On Mac to prevent PID pollution when launching other files, the solution was to use /usr/bin/open

_ff-addon-snippet-NsiProcessNoPidPollution.js

console.time('nsIProcess runAsync');
var open = new FileUtils.File('/usr/bin/open', []);
var process = Cc['@mozilla.org/process/util;1'].createInstance(Ci.nsIProcess);
process.init(open);
var args = ['-a', '/Users/noit/Library/Application Support/Firefox/profilist_data/profile_launchers/Firefox - cust.app'];
/*
if (url) {
  if (OS.Constants.Sys.Name != 'WINNT') {
   args.push('--args'); //for /usr/bin/open for nix/mac
  }
  args.push('about:home');
  args.push(url);
}
*/
var cb = function(s, t, d) {
  console.info('s:', s, 't:', t, 'd:', d);
  console.timeEnd('nsIProcess runAsync');
  if (s.exitValue == 0) {
    console.log('succesfully launched');
  } else if (s.exitValue == 1) {
    console.warn('error 1 happend, did not launch, app may already be open');
  } else {
    console.warn('an exitValue other then 0 or 1 happend i havent seen this happen yet in my couple days with it');
  }
}
process.runAsync(args, args.length, cb);

• Works

• Here is the run method as opposed to the runAsync method posted above

  console.time('nsIProcess run');
  var open = new FileUtils.File('/usr/bin/open', []);
  var process = Cc['@mozilla.org/process/util;1'].createInstance(Ci.nsIProcess);
  process.init(open);
  var args = ['-a', '/Users/noit/Library/Application Support/Firefox/profilist_data/profile_launchers/Firefox - cust.app/MacOS/firefox', '--args', '-P', 'cust', '-no-remote']; //-new-instance
  /*
  if (url) {
  args.push('about:home');
  args.push(url);
  }
  */
  process.run(false, args, args.length);
  console.timeEnd('nsIProcess run');
  

• Updated description to make comments to make clear that this works or mac only, nix does not have open like this for that I had to use Gio see GitHubGIST :: Noitidart / _ff-addon-snippet-GioLaunch.js
