Halo Ylap,
That is exactly like I did it. If you have java installed in FF, update sun java in your configuration console where it says Applet click Mozilla (Firefox is moz.dev) and click Promt user if hinted. If you have an older version of sun java in Program Files delete it. Sometimes applets may like the older version (only if it is available of course). Surf safely and stay away from viruses, malware, scumware,
Pozdrawiam (Greetings)
