I needed Java Runtime Environment....if you go to the Java site there is a page that has a button that checks to see if your computer has the correct Java installed. Firefox couldn't display some information on the page and it said that I needed plugins. When I downloaded the runtime environment I noticed the plugins were being installed so they happen both at once.

So there's the answer...even though you have the correct update for Java installed you still need the runtime environment downlaod and you get that at the java site. Look for the button that checks your system for the correct installs.
