I have uninstalled and reinstalled the plugin and the whole version even the quicktime alternative and it still doesn't want to play mov files. I am going to the apple.com/trailers page to watch some trailers and it gives me an error that I need to update or install the quicktime but it is already installed so anyways I just click on it again and try to reinstalled it then close the browser and open it back up again and same issue... I have tried a lot of things and even have kind of the same issue using chrome but chrome has an option that says play this time or once and I can use that option to watch them anyways but firefox doesn't pleasseeee assist me with this I am a die hard firefox user and installed chrome just to test the quicktime thing...
