I am building a portfolio site (source code available at www.jpgrafx.com/home.html) and have gotten it to run the way I want on Firefox.

When I run it on Safari, however, I get the blue lego icon indicating that a plugin is missing(both browsers running on same computer).

The icon is not accompanied by any information on what plugin is missing.

How can I identify the missing plugin so I can direct Safari users, or better yet make my page cross browser compatable?

I have used JavaScript to display XML data, and the method I used seems to work on both browsers (example available at www.jpgrafx.com/XML_examples/ajax.html).
