AS3 popover code only working in Chrome

I tried that and am still having this issue. It is also happening on these,

separate sites:

http://arthur-chu.com/ (click any of the social media links on the ³eraser²)

http://robinrayeller.com/ (click any of the social media links at the

bottom)

http://www.perrynorton.com/ (click any of the social media links at the

bottom)

I could list lots of others with the same code causing the same issue but

only in Firefox.

I just discovered thought that in an AS2 site that I built,

http://adambehr.com that the popover code that I used works fine in Firefox,

Safari and Chrome. That code is:

on (release) {

var jscommand:String =

"window.open('http://www.youtube.com/user/tundramonkey100/videos?view=1','wi

n','height=559,width=1000,toolbar=no,scrollbars=yes');";

getURL("javascript:" + jscommand + " void(0);");

}
