Java awt Canvas Image is not getting displayed with Mac FireFox 24 and above. The same Canvas image is getting displayed properly with Windows FireFox. Please find the code snippet below.

Is this an issue with FireFox or any extra steps needed in Mac to make this working ?

public class CanvasSample extends Applet

{

  public void init() {
   this.add(new RedOval());
 }

}

class RedOval extends Canvas {

 public void paint(Graphics g) {
   Dimension d = this.getSize();
   g.setColor(Color.red); 
   g.fillOval(0, 0, d.width, d.height);
 }
 public Dimension getMinimumSize() {
   return new Dimension(50, 100);
 }
 public Dimension getPreferredSize() {
   return new Dimension(150, 300);
 }
 public Dimension getMaximumSize() {
   return new Dimension(200, 400);
 }

}
