User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:51.0) Gecko/20100101 Firefox/51.0
Build ID: 20170125094131
Steps to reproduce:
Works for me in different OS and various Version of Fox.
Steps to reproduce :
1. Open black.html OR
http://hackies.in/black.html
I accept i made this for DOS'ing fox , but it doesn't gets DOS however when we refresh the script tab again and again after few times the browser becomes normal but at that time every website which is visited in different tabs the page becomes black.
I might not be able to explain well, but the video POC attached below may help a bit.
I am just refreshing the black.html tab 2-3 times where the browser didn't gets DOS but after that all the page which are visited becomes black.
Actual results:
Code:
<html>
<head>
<title></title>
</head>
<body></body>
<script>
function e(x)
{
document.body.innerHTML += x;
e(x + 'x');
};
e('x')
</script>
</html>
Looks like a Visual Bug to me.

I get a notification bar that says "a webpage is slowing down your browser", and if I click "Stop It", twice, the problem goes away. I think this is pretty much behaving as expected.
Bill, do you see anything else we can do here?

Summary: innerHTML make the page pitch black → Hanging one tab with infinite recursion causes other tabs to go black when e10s is turned on
Well, the screen going black is a bug. We should be showing the spinner if we can't paint actual web content.
It looks like it's not easy to reproduce, but the video makes it pretty clear that it's happening.
