Firefox/Chrome/IE "Running Script Error"

Since my return I have lost more than half of WW2 games because of browser freezing due to the following error, experienced on all 3 browsers mentioned above. What could be the cause? It doesn't always happen, for example yesterday I was using IE and on around turn 18-20 the browser started freezing, like screen is just there not letting me move anything (Music is playing) then after a few seconds I can move units again, etc. Fucking my turn up. I didn't take a SS of the error but I got it many times and it's the same thing. This is what it looks like for Firefox, for example:




on IE it's different looking, with only 2 options but basically the same thing

I also reinstalled Windows yesterday so I doubt it's a problem on my end. And installed/updated IE 11 fresh

Anyone else has this problem?

Use chrome

We don't use that particular script, so it's most likely something on your side.

As Amok pointed out - it is on your side, be sure to scan your PC
