Movie is shown very small Firefox (width="100%" and height="100%)

movie is shown very small Firefox (width=“100%” and height="100%)

I configured the movie width=“100%” and height="100% to wide spread the screen , and this happens normally to IE7 and Opera.
However with Firefox the movie is shown very small.
does someone know why ?
Thank you
