For an unknown reason, the Preferences window was not appearing on Version 1.8.

The jsjbridge.jar Version 1.8 Java library:

• Embed JSON code to remove the external json.jar dependency.
  
• Retry waits for request replies when the thread is interrupted.
  

Trigger a JavaScript window.jsjbridgeActive event when the JSJBridge code has been loaded and getElementById calls return a Java proxy rather than a normal HTML element.

Code can now be like

addEventListener('jsjbridgeActive', function() {
var myHelper = document.getElementById('myApplet');
myHelper.addEventListener('initialized', function() { ... });
});

instead of

var myHelper = document.getElementById('myApplet');
myHelper.addEventListener('initialized', function() {
myHelper = document.getElementById('myApplet');
...
});

Disable the ability of Java to call eval on a JavaScript string. Mozilla believes this original feature of JSObject to be a security risk. It is still present on the Chrome/Chromium extension.
