Question

I download the file with usage of the 1st code here.
How can I wait (i.e. run request as synchronous) or know when download is finished?

Upd. Ok, looks like I should do something like:

myfunction = function(url) {
// downloading file here

  persist.progressListener = {
    onStateChange: function(aWebProgress, aRequest, aStateFlags, aStatus) {
      if (aStatus == STATE_STOP) {

      }
    }
  }
// once download is finished, myfunction should return result
}

How myfunction can return result, if I use listener?
