I upgraded to Quicktime 7.7.9 but it won't play Apple trailers

Also me... Last version of quicktime don't install quicktime plugin in firefox browser so video trailers are not playable. In other browser (IE) movies are playable

I'm on a MBA 2013, and the latest firefox version is NOT playing apple trailers anymore even with the latest quicktime add-on. It just tells me to move over to Safari. What the ****? It's like, you buy an apple and apple apple apple apple. Aren't we waaaay beyond that? I mean...I got the internet, and I can do without apple trailers if that's how you're gonna play it Apple. come ON now. IT'S FIREFOX. They are a zero threat to your business model.

But it won't play on safari I always right click the video to download the trailer on QUictime but now the options gone! Please put the option back!!! I LOVED USING the QUictime because i love stepping between pause button. PLEASE! I already have saved quicktime and were else can i download QUcitime HD trailers?! Please put QUcktime HD option back on Apple.http://trailers.apple.comtrailer pages such as Zootopia and every other future movie.
