Best way to refresh page with this same Scene

[hw3web]

What is the best way to empty memory from reloading this same scene to not double memory slot.

 

I realize that each time I refresh page consumption of memory just adding. I try:

 

var engine = null;

var scene = null;

 

or 

 

if (scene) {

    scene.dispose();

    scene = null;

}

 

 

is there any other, best way to dump from memory scene and engine  before start again this same or just remove any other so they not use memory and CPU!?

Or is there bug in firefox as in chromium refresh not add any consumption of memory ??? - I am bit confuse(.com ).
