I wanna try to explain with an example, i have to pages A.html and
B.html, the page A open the page B in a separated intance of the
browser, i need to refresh the page A every five minute. Actually i
doing with the setTimeout function, but when the page A is refresh

I should think that a simple <meta refresh> would do the trick:

<meta http=equiv="Ref resh" content="300; URL=http://www.htmlhelp.co m/">

That your browser is allowing a JavaScript refresh to invoke a change in
focus sounds wrong to me. an old School refresh should do what you want.

It was never said that the new instance was opened with JavaScript.
However, this appears to be the only near-to-reliable way to achieve
a timed refresh of another window without focusing it.

Unlikely. If the user agent focuses all refreshing windows which is
BTW legitimate behavior, your solution will not help then. Besides,
http-equiv="refresh" is described both in the WDG HTML 4 Reference
and in the HTML 4.01 Specification as "Not all browsers support this"
and "some user agents support it" which indicates that it could fail.

You cannot know this. Popups can be opened in tabs.

I assume you have the following code in "page" A:

var b = window.open(... );

Append

if (typeof setInterval != "undefined" )
{
setInterval(
"if (!!b && !b.closed && b.location && b.location.relo ad)"
+ "{ b.location.relo ad(); if (b.blur) b.blur();"
+ "if (self && self.focus) self.focus(); }",
5 * 60 * 1000); /* every five minutes; in practice,
use the computed value instead */
}

and you should be done.
