I was forced to disable a11y crashtests (all platforms faulire) and test_getChildAtPoint.xul (linux failure). linux: http://tinderbox.mozilla.org/showlog.cgi?log=Firefox/1236226389.1236234660.7122.gz mac: http://tinderbox.mozilla.org/showlog.cgi?log=Firefox/1236226799.1236233592.5011.gz win: http://tinderbox.mozilla.org/showlog.cgi?log=Firefox/1236226389.1236233318.4604.gz It sounds crashtests doesn't like enabled a11y.
