Hi, I just upgraded my FF to 8.0.1. When I was trying to launch one of the downloadable 1080p trailers on this site: http://trailers.apple.com/trailers/w...rkknightrises/ It wouldn't launch the quicktime app outside of FF. Usually the downloadable 1080p trailer plays in QT outside of FF. The previous FF worked fine with this. My other Macbook Pro has the same v8.0.1, it launches QT trailer outside of FF just fine. I think something is not right with my FF. All other FF browsing function seems to be normal. Can someone help? Thanks.
