Status: RESOLVED DUPLICATE of bug 1263155

(Toolkit Graveyard :: Notifications and Alerts, defect)

Description

[janekptacijarabaci]

User Agent: Opera/9.80 (Windows NT 6.1; WOW64) Presto/2.12.388 Version/12.18

Steps to reproduce:

Tested on:
Firefox 38 - 52.0a1 (2016-09-30)
Windows 7/8
Ubuntu 16.04

Confirmed on:
Windows 7/8 (does not work)

Not confirmed on:
Ubuntu 16.04 (works)

1) Open Scratchpad

2) Menu: "Environment-Content" (if it is allowed - Notification.permission) or "Environment-Browser"

3) Insert the code:

var repeat = 2;

// var type = 2;
var type = 1;

var timeout = 500;

if (type == 1) {
  var i = 1;
  var interval = window.setInterval(function () {
    new Notification("Hi! " + i.toString() + " " + (new Date).getTime(), {});
    if (i++ == repeat) {
      window.clearInterval(interval);
    }
  }, timeout);
} else if (type == 2) {
  for (var i = 0; i < repeat; i++) {
    window.setTimeout(function () {
      new Notification("Hi! " + i.toString() + " " + (new Date).getTime(), {});
    }, timeout);
  }
}

4) Run
5) The result:

[type == 1]
It shows 2 notifications. Also after rerunning.

[type == 2]
Nothing is displayed.
Just a shadow of "notification" (for Firefox 45+) - in the top right of the screen (after closing "notification"... this shadow disappears).
Those notifications are probably in the top (and not see this).
