alert(item.getAttribute("value"));       // alerts correct value

Technically this might be the same problem as for bug 294029

This bug was reported on Firefox 2.x or older, which is no longer supported and will not be receiving any more updates. I strongly suggest that you update to Firefox 3.6.3 or later, update your plugins (flash, adobe, etc.), and retest in a new profile. If you still see the issue with the updated Firefox, please post here. Otherwise, please close as RESOLVED > WORKSFORME

This bug is still reproducable in the latest 1.9.3 trunk and IMHO a dup of bug 250123. While it's a XUL problem only it doesn't has anything to do with the named plugins.

This bug is still reproducible on FF4.

I've wasted 2 hours debugging on this one. VERY frustrating...
