A good place to look for a plugin for your browser is at the San Diego Supercomputer VRML Repository. They have links to websites for a large number of VRML plugins and applications that are under development.

If you have not downloaded and installed a VRML viewer, you must have the installation completed before you can proceed to see the exhibits.
