676881 - escape key closes open websocket in Firefox

Status: RESOLVED DUPLICATE of bug 614304

(Firefox :: General, defect)

Description

[TeeTeeHaa]

Attachment: index.html

User Agent: Mozilla/5.0 (Windows NT 6.0; WOW64; rv:5.0) Gecko/20100101 Firefox/5.0
Build ID: 20110615151330

Steps to reproduce:

Pressed escape key in Firefox while a websocket connection was open.


Actual results:

The websocket connection was closed. This happened in Firefox 5 on Windows Vista 64 Bit and Windows 7 64 Bit. This did not happen in Chrome or Opera. A test case is attached (index.html). In case this is not a bug I'd love to know how to prevent it anyway (in JavaScript). There already is a similar (but not the same) bug: "614304 - ESC key aborts XMLHttpRequest"


Expected results:

The websocket connection should have stayed open.

I get this error message in Firefox:
[19:51:02.337] WebSocket is not defined @ https://bug676881.bugzilla.mozilla.org/attachment.cgi?id=551078:9

Something I'm missing? Chromium is a WFM.

Attachment: partial fix for the symptom of the initial test case

I found a partial fix for the symptom (attachment 551253 [details], file "partialsymptomfix.html"). It uses jQuery and it prevents the websocket from being closed at least in case the document has the focus.

In Firefox 4 and 5 the websockets implementation is disabled by default due to security reasons and you have to override this to enable websockets. Please read the red box on the bottom of the following website:

This issue is still present in Firefox 8, where websockets are enabled by default. Is it possible to get this fixed?

Looks like this is related possible to the things mentioned in this bug: https://bugzilla.mozilla.org/show_bug.cgi?id=614304
