Is there a Ubuntu compatible version of the "Adobe Shockwave Player?" I'm running Firefox and when I try to bring up one of my School's websites it says missing plugin. When I click on "Install missing plug-in" it says none found, so when I click on manually install plug-in it takes me to Adobe Shockwave Player installation, but there is no ubuntu version to install??? On the Firefox plug-in finder service it says "Unknown Plugin (application/x-director)
