What plug-in would I need for Firefox to see the same animation as on IE (see below)?

I noticed the animation to the Haloween theme, in the upper left corner, on the Yahoo home page when using IE7. However, there is no animation when I go to this page using Firefox 2.0. I have Adobe flash on IE and I tried downloading it for Firefox but there was no change. The animation to the ad for the movie "Deja Vu" is the same on both browsers.

What plug-in would I need for Firefox to see the same animation as on IE (see below)?windows media player
