I'm trying to find out myself, but I'm not a web-developer.  
If I press F12 in Firefox, there are many warning listed, but no blocking errors.

It's probably not related but found a tiny bug at the function of 541. line:  
_(heatmap is turned off)_

```js
// Remove old markers
function doTidyUp(l) {
    if (l === "heatmap") {
        heat.setLatLngs([]); // << HERE is the problem!

(TypeError: heat is undefined
    doTidyUp worldmap.js:544

```
