370225 - child browser window opened via js cannot focus on parent via window.opener.focus

Status: RESOLVED INCOMPLETE

(Firefox :: Tabbed Browser, defect)

Description

[Valentyn Gatsuk]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-US; rv:1.8.1.1) Gecko/20061208 Firefox/2.0.0.1
Build Identifier: Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-US; rv:1.8.1.1) Gecko/20061208 Firefox/2.0.0.1

I use javascript to create new child window and set its opener as in:

<script language=javascript>
function openWindow() {
BFWin = open('display/somepage.php', 'BFWin');
BFWin.opener = window;
}
</script>

After that in child window, I try to focus on parent window using javascript:

        <script language=javascript>
        function focusOnParent() {  
        var pw = window.opener;
          if (pw && !pw.closed ) {
            //pw.alert('wha?');
            window.blur();
            pw.focus();
            window.close();
          } 
        }
        </script>

Note if I uncomment pw.alert line - it works and alerts the right parent tab, meaning I have a correct parent object window as opener. 

However if I call the function on child window - it closes child and goes to the right-most opened tab INSTEAD of parent. Very uncool.

So js window.opener.focus() doesn't work in FF 2.0.0.1 (linux ubuntu OS)

Reproducible: Always

Steps to Reproduce:
1. see details

Actual Results:  
right-most tab gains focus instead of parent

Expected Results:  
parent tab should gain focus

Make sure you have "Options > Content > Advanced > Allow scripts to: raise or lower windows" checked.  Depending on the event (see bug 355482), web pages are not always allowed to call focus() by default.

Btw, you don't need the line "BFWin.opener = window;".  The "opener" property is set automatically.

Hey guys, I run into same bug. I can't bring focus on parent window from child.

OS: MacOS 10.12.6 (16G1036)
Firefox: 57.0.1 (64-bit)

Could you please confirm is it some security block, or a bug that should be fixed?
