title: applet blocked due to security settings
body: <p>My web app uses an Applet during the login process. Everything was working fine until today when I was prompted to update from version 1.7.0.45 of the Java Firefox plugin to version 1.7.0.51.</p>
  
  <p>I declined this invitation, but shortly after doing so, the login stopped working. If I open the Java console and try to call the Applet from Firebug I see the following messages:</p>
  
  <pre><code>security: LiveConnect (JavaScript) blocked due to security settings.
  network: Created version ID: 1.7.0.45
  network: Created version ID: 1.7.0.51
  </code></pre>
  
  <p>So it seems I'm trapped in some purgatory between the two versions. My is guess that either:</p>
  
  <ul>
  <li>the partial installation of 1.7.0.51 changed some security settings which are preventing me from calling the applet (from JavaScript)</li>
  <li>I can't call the applet because the old version is blocked and I have to upgrade to the newer version</li>
  </ul>
  
  <p>If possible, I'd like to go back to version 1.7.0.45, and my previous security settings, because I know this configuration worked. If this is not possible, then I guess I'll try to upgrade to 1.7.0.51. I checked in the Java control panel for a way to upgrade, but there doesn't seem to be any "check for updates now" button. I'm using Firefox 26.0 on a Mac running OS 10.8.5. </p>
