Lets say we have a page that dynamically adds iframes to show information. because the user shall print them out there is a print button that does window.frames['name'].print().
This does work in all browsers, but in none of my tested firefox builds (2-3.5rc)
however window.frames.length is always 1. and additionally window.frames[0].print() does work always as well.
My assumption is that the named registry still refers to the old no longer existing iframe, eventhough the new one is there already. See attached html to reproduce
Reproducible: Always
Steps to Reproduce:
1. Open Testscript, press the "rebuild iframe" button once. (note that inner.html needs to exist)
2. Press "show location"
3. Press "rebuild iframe" again
4. Press "show location" again
Actual Results:
1. an iframe is created
2. the url of inner.html is displayed
3. the iframe is deleted and recreated
4. nothing happens
Expected Results:
1.-3. same
4. again the url is displayed
The workaround is:
var myFrame;
for (i=0; i < window.frames.length; i++) {
if (window.frames[i].name == 'myIframe') myFrame=window.frames[i];
}
but the original bug could also indicate a memory leak

Same thing occurring for me. I actually created a very similar test page to demonstrate that closely resembles yours...
<html>
<head>
<title>FF Bug</title>
<script languague="Javascript">
function createFrame() {
if (document.getElementById('if1') != null)
document.body.removeChild(document.getElementById('if1'));
var el = document.createElement("iframe");
el.setAttribute('id', 'if1');
el.setAttribute('name', 'if1');
document.body.appendChild(el);
}
function checkFrame() {
alert(window.frames['if1'].location.href);
}
</script>
</head>
<body>
<input type="button" value="Create Frame" onclick="createFrame();" />
<input type="button" value="Check Frame" onclick="checkFrame();" />
</body>
</html>
