Load it up in IE and try to use the component selector. Says bug on line 73: function PutDescription() { if ((document.getElementById) && (document.body.innerHTML)) { var componentIndex = document.getElementById('component').selectedIndex; if (componentIndex != -1) { var description = document.getElementById('description'); //73 description.innerHTML = descriptions[componentIndex]; } } } lectedIndex; PS, adding windows and other OS selectors to the OS dropdown in your bugzilla!
The component selector is also broken on bugzilla.mozilla.org, so it either looks like they intended this, or it is truly a bugzilla bug. Perhaps using a more compatible browser would be your best choice.
