I've got the same error message trying to do something like this in JavaScript:


pXML=loadXMLDoc('test.xml');
galleries = pXML.getElementsByTagName('gallery');

for (var i=0;i<galleries.length;;i++) {
        if (galleries[i].nodeType != 1) continue;
...
}

and in this place I've got error 
"Permission denied to get property Element.tagName"

In FF 2.x all works properly.

Reproducible: Always

Is there planned any releases or patch in order to remove this bug?
Note that is is probably a duplicate of bug 440422.

A patch would appear in this bug but that usually only happens if this bug gets confirmed as valif bug but the bug is still marked unconfirmed.

Depends on: 434522
I cannot reproduce the issue - neither with http://dev.abiss.gr/sarissa/test/testsarissa.html nor with the attached testcase. Testing in Firefox 3.0.1 and Gecko/2008080303 Minefield/3.1a2pre.

I can still reproduce with a slightly older build (latest release?).

Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.4; en-US; rv:1.9.0.1) Gecko/2008070206 Firefox/3.0.1

It could be related to Firebug plugin.

Probably a duplicate of Bug 440275 or Bug 434522, etc there are a lot of them. Bet its fixed in 3.0.2.

Demo of bug, complete with screenshots and description.  Enough to confirm bug.

Submittal consists of a directory tree w/ HTML source plus notes and screenshots.  Zipped (loosely) so that WindBlows Extraction Buzzard can handle it.

The bug shows up under  file://  protocol on local computer, but not  http://  from a web-site.

There's an oddity in the Error Console Message that I mention in the Notes; I suspect it might be worth following-up.

Please examine this submittal and confirm the bug...

Supplement to test case:  Shows error when in a parent dir as well.

This attachment updates the MainDir/index.html and the four iframe.html files to demo the problem in an additional case, i.e., when the iframe-source file is in the parent-dir of the principal file.  Also, it corrects a slight (but irrelevant) flaw, thus verifying that the bug was not caused by that.

Again, the bug only appears when the  MainDir/index.html  file is loaded from the local filesystem...

I am not so sure now if the bug I described here is related to the bug originally filed under this Report, or if it is more appropriately related to Bug 442015.  Please look there for follow-up.
