User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:35.0) Gecko/20100101 Firefox/35.0
Build ID: 20141012030203

Steps to reproduce:

1) Go to http://en.lichess.org/
2) Click `Play with the machine' (or any other means of playing a chess game)
3) Start the game


Actual results:

Nightly (both 2014-10-11 and 2014-10-12) crashes.


Expected results:

The chess game should be playable as it was with the 2014-10-10 and previous Nightlies.

It crashes in  [@ mozilla::OffTheBooksMutex::Lock() ] which is bug 1067348 but I guess it masks the real crash signature (different regression ranges).

In a local debug build on Linux64:
Assertion failure: mImpl, at content/base/src/WebSocket.cpp:2152
Component: General → Networking: WebSockets
Keywords: assertion
OS: Windows 8.1 → All
Looks like a regression from bug 504553?

What prevents a WebSocket still being visible from script after WebSocketImpl::Disconnect happens, exactly?

I'm not sure which browser tab happens to be the triggering cause (likely either Feedly or Washington Post, I could imagine either of them doing this), but nightly builds are unusable for me with this in place -- I crash a matter of minutes every time.

Particularly given we're cutting a branch Real Soon Now, could we back out those patches and reland with this issue fixed?
Summary: Website (lichess.org) constantly crashes after recent Nightly (2014-10-11) → Constant crashes on lichess.org after 20141011 Nightly [@ mozilla::dom::WebSocket::ReadyState() ]
Another Website using the new feature that doesn't work, yet:
www.runescape.com/game?html5=true

It just keeps on loading, so I guess that there might be some issues left still.

Could also be that the reason for this is, that Runescape got mostly optimized for Chrome, since Websockets in Webworkers were missing in the past, so that they couldn't test it with FF.
Might be the case though that the reason is that Firefox blocks Cross-Origin requests.
(took a quick look at the console that revealed this error)

My fault. WebSocket tests has to be disabled for android and b2g.

I reproduced this on an OpenStack/Nova Console page (leaving the Console page).

could you pls set the target milestone to 35?
I mean Websockets in Webworkers was introduced in that nightly version, now it's aurora so I guess it makes sense to fix it in the version it was introduced in and not later (we would introduce an unnecessary bug in the release which is there for one month)
Andrea, could you fill the uplift request for aurora (35) asap? This bug is blocking the aurora updates. Thanks

Target milestone on fixed bugs is the version of m-c when the bug was fixed.  Backports (like in 35 in this case) are tracked via the release flags.
