Notes
Reported to be supported in some Android 4.x browsers, including Sony Xperia S, Sony TX and HTC.
Partial support in older browsers refers to the websockets implementation using an older version of the protocol and/or the implementation being disabled by default (due to security issues with the older protocol).
Partial support in older browsers refers to lacking support for binary data.
- * Partial support with prefix.
Bugs
Firefox 37 and lower cannot host a WebSocket within a WebWorker context
