1081458 - Unable to close tab or window when onbeforeunload tab-modal dialog cycling on document.location.href

Status: RESOLVED DUPLICATE of bug 1046022

(Firefox :: Tabbed Browser, defect)

Description

[Harry Richards]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:32.0) Gecko/20100101 Firefox/32.0
Build ID: 20140923175406

Steps to reproduce:

Go to page:

http://www.imagesnake.com/ad.html
(An image host dumps you into this when you close another tab or window.)

Try to close the window or tab.


Actual results:

Some other text momentarily appears offering you the choice of leaving or staying on the page. The text does not stay on screen long enough for you to make a choice.


Expected results:

The text should stay on screen and you should be able to click "leave" to close the tab or window.

Please, you should say when the link is NSFW. I don't care personally, but not necessarily the other people using Bugzilla.

It's a side effect of:
Tim Taubert — Bug 616853 - Make the beforeunload prompt tab-modal r=dao,bz

Simple testcase:
<script>
var exit=true;
window.onbeforeunload = function () {   
if (exit==true) {	
 	location.replace(document.location.href);   
 	return "Hello";
}
}
</script>

That's bad, I can't even close the browser because of tab cycling.

Is that the same as bug 1046022 which we fixed for Firefox 34?

Loic, is that fixed with Firefox 34?

Weird, in general, I check alpha versions before running mozreg or searching a tescase, I forgot. Yes, it's fixed in FF34+.
