I looked but nothing there. Just in the middle of the page in one of the frames is where this gray square it with the statement A plugin is needed to display this content.

I have tried refreshing and clicking every where within that frame and on the lego block looking battery you suggested but nothing happens.

I take it this is a inframe area and not the whole page so it wont show up at the top but in the frame. but nothing in the frame will give me what type of plugin. Thanks

Here is the instructors site but you wont be able to get in with out an account to log in with.

The web page tries to embed an HTML document via the EMBED tag. Unfortunately this doesn't work in Firefox. In Firefox only the OBJECT tag and an IFRAME can be used to embed an HTML document.
