title: Browser Plug-ins Not Loading in WebView Implementation
body: <p>I have a Cocoa app that I'm trying to write which displays a webpage. This webpage has an embedded quartz composition in the background that plays and works when in Safari, but it does show in my Cocoa application (it just shows the missing plugin icon in the background instead).</p>
  
  <p>The weird thing is that it works on another computer that I was testing it on. Am I missing a framework or a plugin somewhere that might cause this?</p>
  
  <p>Another note: no plug-ins seem to work. For example, when the WebView displays youtube.com it is unable to play video because it says that Flash Plugin is not installed. Again, the same code works on another computer, but not this one.</p>
  
  <p>Thanks! Any help would be greatly appreciated!</p>
