title: How to set window.opener in Firefox
body: <p>I have old code, which uses window.opener. I changed opening method of these pages from popup to iframe in a jquery dialog. That works fine with IE and Chrome, where I only need to reset window.opener in onload event. But Firefox does not play ball. It sets opener to null regardless what the opener was or is to be set (which is ludicrous). Is there a way to change window.opener in Firefox? I known I could work around it by storing the opener information elsewhere, but it takes a lot of more changes.</p>
