in Firefox,tips and tricks

Due to security issues in WebSockets protocol, Firefox and Opera turned off support for WebSockets for their next releases Firefox 4 and Opera 11.  We’ve covered how to enable WebSockets in Opera 11. Firefox 4 Beta 8 will be released with WebSockets support disabled by default, if you want to experiment with WebSockets in Firefox 4, here is how to do that.

Enabling WebSockets in Firefox 4 Beta 8

1. Type about:config in address bar, and continue by clicking “I’ll be careful, I promise”

2. Set network.websocket.enabled  value to ‘true’ and set network.websocket.override-security-block preferences to ‘true’.

3. Restart Firefox browser.

You don’t need to turn on websockets in Firefox 6 because its enabled by default.
