Firefox 19中不支持WebSockets？

Question

i am trying to write a websocket page, and it works in Chrome and some other browsers on my Ubuntu machine. however, firefox would not run the websocket part, and both window[WebSocket] and window[MozWebSocket] return "undefined". does firefox not support websockets?

Answer 1

Use (from MDN docs ):

var mySocket = new WebSocket("ws://www.example.com/socketserver", "protocol");

It is supported from Firefox 6.0 (known as MozWebSocket prior to Fx 11 - see @Dracs' comment).

Answer 2

Extensions like TorButton can set network.websocket.enabled to false in about:config . Make sure it's true .
