Attachment: alert_applet_example.rar

User Agent: Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; Trident/6.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; MALC)

Steps to reproduce:

I have an applet button that call a javascript function that show an alert message.


Actual results:

I notice a strange focus problem in Firefox 21 (not in previous versions).
Alert appear only when I click Firefox icon in task bar.

I've made a very short video : https://vimeo.com/66647009

Here you can download a very simple example :

I've put all files that I've used but you only need :
1) test.htm
2) JavaToJavaScript.jar


Expected results:

Should simply show alert message

If i get this right from the video... the problem is that, when you try to show an alert from Java, it doesn't show until you refocus or hide/show the Firefox window?

Exactly. Call javascript function (that show an alert) by clicking an applet button.

You can download the Attachment to see a working example.

Same behaviour here with another applet that calls javascript to show an alert.  Alert is hidden and shows up when changing to another task and returning to firefox (Alt-Tab)

Same here.
The problem seems to be related with netscape.javascript.JSObject.
If the javascript protocol is used, there's no problem.

Is this still happening in current Firefox Nightly builds?

Nope.
With FF 25.0a1 (2013-08-04) the alert works as expected.
For tracking info: this bug was introduced in FF 18/19. FF 17 works fine.

Great, thanks for checking.
This makes it likely to be also caused by bug 785348, although i'm not sure which dependency is likely to have fixed this.

Hello.
