Plug in missing????

Had to initialize hd because of a prob. With mountain lion.
Got all back up and running BUT ? I have a web site--www.radar.weather.gov that I ck. surrounding weather on. It is a radar site. Now when I want to " loop"
The radar screen-put it in motion I get a message that "a plug in is missing", so now I can't loop the radar.
Any one got an idea how to fix this ? Is it a java plugin?
I am not familiar with how plug ins work.
Thanks

Plug in missing

PROBLEM SOLVED !!
The webamaster at the weather web site wrote me back today.---I NEEDED "ADOBE FLASH PLAYER" INSTALLED. I DOWNLOADED IT AND INSTALLED AND THAT FIXED THE PROB.
