What seems to be happening most of the time though, is that it recognizes that I need Apple Quicktime, but it cannot install it automatically, so it gives me the link to the site so that I can install it manually.
However, I already have quicktime on my computer. I tried updating it, and I even reinstalled it from the site that they gave me, but the missing plugin bar always reappears when I go back to that particular site. And I do notice that some aspects of the website, be it MIDI background music or embedded videos, do not play.
How can I get this plugin to work for firefox? Is there something I'm doing wrong? Or is this just another glitch?
