User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:40.0) Gecko/20100101 Firefox/40.0
Build ID: 20150812163655

Steps to reproduce:

When Electrolysis is enabled with particular privacy preferences, eg:
  - cookies accepted,
  - third party cookies refused (don't think it as a real influence, but I precise !)
  - conservation: keep until MUST BE "ask me everytime".
Then go to a new site where you do not have any cookie and wait for the pop-up that will ask you what to do with.
NB: You have to go to a site where you don't have any cookie in your exception list, and more cookie the site sends, better it is for this demonstration


Actual results:

Firefox Developer Edition crashes, not just the actual tab, but all the browser


Expected results:

See the pop-up that asks what to do with the cookies

I managed to reproduce it on the 20150824 Nightly build ( https://crash-stats.mozilla.com/report/index/2093b19e-40d9-4ef7-9d85-ad7f32150827 ), but I cannot reproduce on today's builds (20150827), neither on Central nor DE.

The strangest thing is that when I then retried with previous builds (20150826 back to 20150823), both Central and DE, to find out when it could be accidentally fixed, I could not reproduce anymore ?:/

Can you still reproduce after upgrading to latest build?

It happened again today with imgur.com (exact link if it can help: http://imgur.com/gallery/bl6HPR7
) on build "42.0a2 (2015-08-29)" (Dev Edition)
I have register the crash log, and I'll attach it to the bug, when I will finally find how to do it (I hope it will help) !

But, yes, it does not happen every time now, it makes more and more rare, but still happen sometimes.

This is the log of the latest crash that happened on my computer

I crashed with the latest Nightly, but it's hard to reproduce.
https://crash-stats.mozilla.com/report/index/17708446-3d55-4822-b167-752802150831
The crash occured when I was browsing another tab while a permission cookie pop-up appeared from the other tab.

Maybe we need to find accurate STR.

I found STR and I think this bug is a dupe of bug 1185734.
Could you test my STR here: https://bugzilla.mozilla.org/show_bug.cgi?id=1185734#c1

Why do you think this is a dupe? This is crashing on a different IPC_ASSERT:
    IPC_ASSERT(mCxxStackFrames.empty(), "mismatched CxxStackFrame ctor/dtors");

Oh, I see, comment 1 here has a crash that looks like the other bug.

Yes, I think this is well a dupe of the other bug 1185734.
The only thing changing with your steps is that in my case, I don't even need to go back to the OS desktop before the crash, just have to wait. And after opening the link, it just freezes and then crashes !

Yes, maybe I'm wrong. Indeed, I thought it was a dupe because when finding STR for this bug, I crashed with the same signature as bug 1185734.
