Java awt Canvas image is not getting visible with Mac FireFox 24 and above version. The same Canvas image is displaying properly with Windows FireFox 24 and above.

Please let us know, is there any extra steps needed to make this working or is this an issue with Mac FireFox ? 

public class CanvasExample extends Applet
{
   public void init() {
    this.add(new RedOval());
  }

  public Dimension getMinimumSize() {
    return new Dimension(50, 100);
  }

  public Dimension getPreferredSize() {
    return new Dimension(150, 300);
  }

  public Dimension getMaximumSize() {
    return new Dimension(200, 400);
  }
}

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);

  }
}

I would recommend you file a bug at https://bugzilla.mozilla.org/ using all the information you have given here. And I will do my best to have a developer comment on it. This is outside most volunteers knowledge.

Please post the bug link here after you have created the bug.

The closest report I could find on this was: http://stackoverflow.com/questions/22247304/mac-osx-appletviewer-doesnt-display-anything
