You can make the big snow working in firefox by modify this script

find

else if (ns6up){
document.getElementById("dot"+i).style.top=yp[i];
document.getElementById("dot"+i).style.left=xp[i] + am[i]*Math.sin(dx[i]);

replace with this

else if (ns6up){
document.getElementById("dot"+i).style.top=yp[i]+'px';
document.getElementById("dot"+i).style.left=xp[i] + am[i]*Math.sin(dx[i])+'px';
