On Firefox, does not render. 'canvas' stopped

Hello, I have an issue with firefox but the other browser works fine(even IE, MS Edge).
With below codes, I have only black screen.
But sometimes (when I replaced render(); to renderer.render(scene, camera);) , it works fine.

On chrome, or any other browser, works fine but only firefox does not work.
++
But site still alive. I checked it with'mousedown' -> console.log('alive?');event.

I’m using three.js r112, and firefox 72.0.2.

function animate()
{
	stats.update();
				
	render();		 
				
	requestAnimationFrame( animate );
}

function render()
{
	//201754
//	console.log(renderer.info.render);

	raycaster.setFromCamera(mouse, camera);
	
	var intersects = raycaster.intersectObjects( scene.children, true );
	
	if ( intersects.length > 0 )
	{
		if( __CLICKNAMES__.indexOf(intersects[0].object.name) != -1)
		{
			if (INSECTED != intersects[ 0 ].object) {
				if( INSECTED ) INSECTED.material[0] = INSECTEDMaterial;
				
				INSECTED = intersects[ 0 ].object;
				INSECTEDMaterial = INSECTED.material[0]
				INSECTED.material[0] = new THREE.MeshLambertMaterial( { color: 0x9986EE, emissiveIntensity: 0.5 } ); 
			}
		}
		else
		{
			if( INSECTED ) INSECTED.material[0] = INSECTEDMaterial;
		
			INSECTED = null;
		}
	} else {
		if( INSECTED ) INSECTED.material[0] = INSECTEDMaterial;
		
		INSECTED = null;
	}
	
	renderer.render( scene, camera );
}

I only updated renderer.render()scene, camera); to render() function, and it does not work.

I just followed https://threejs.org/examples/?q=cube#webgl_interactive_cubes

Sorry, but I’m afraid your question is not very clear. Please demonstrate the problem with Firefox by changing this live example so it reproduces the issue:
