Add support for CSSStyleProperties, so it works on Firefox versions from 144.

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.
