I am wondering if it is possible to embed Firefox browser as a component in a Java Swing based application.
I have done a bit of research from the Internet, but I could not find an answer. Some people suggest to use other browser component available in Java. I do not think that is preferable, as the rendering engine would be different to Firefox.
Any idea? Many thanks.

Not directly. You could port your UI (or at least part of it) to SWT and then use the Browser component (see this FAQ item).
If you can't port your UI to SWT, then you can embed your Swing UI in SWT (SWT Shell
== Swing JFrame
). But there will be some pain ahead.
Update: Firefox is no longer supported by SWT. Currently supported is the system's default browser or WebKit (see https://github.com/eclipse/eclipse.platform.swt/search?q=BrowserFactory&unscoped_q=BrowserFactory).

As answered here (Best Java/Swing browser component?) - and from my own testing - djproject seems to be the best.
It has last been updated March 2009 and some demo links are broken.. so the project seems not to be too active right now.. Still: When I needed it in 2010 it was awesome.

Absolutely I have done it before please check out the Mozilla Embedding for Java
Here is some sample code
import java.awt.Color;
import java.awt.Component;
import java.awt.Container;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.FileNotFoundException;
import java.io.File;
import javax.swing.*;
import org.mozilla.xpcom.*;
import org.mozilla.interfaces.*;

How about embedding your GUI inside the browser instead, with an applet, GWT or another rich client approach?
