and toolkit/components/url-classifier/tests/mochitest/test_classifier.html and toolkit/components/url-classifier/tests/mochitest/test_classifier_worker.html both fail with:
"not ok - Error thrown during test: document.getElementById("testFrame") is null got 0, expected 1"
So, I wasn't able to reproduce the test_bug445004.html failure but toolkit/ components/ places/ tests/test_ bug_411966. html seems to fail reliably with:
"not ok - Got wrong referrer for http:// localhost: 8888/tests/ toolkit/ components/ places/ tests/bug_ 411966/ PermRedirectPag e.htm"
and toolkit/ components/ url-classifier/ tests/mochitest /test_classifie r.html and toolkit/ components/ url-classifier/ tests/mochitest /test_classifie r_worker. html both fail with:
"not ok - Error thrown during test: document. getElementById( "testFrame" ) is null got 0, expected 1"
