Nice and clean WS client extension. I really like it. But for 5 stars I would like to see a lfew more features like being able to extend/drag the 'message text' field (it is pretty small) and some 'clear history' would be nice.

Shame, wanted to use it but can't use custom ports: Unable to open connection: SecurityError: Failed to construct 'WebSocket': The port 6667 is not allowed.

Unfortunately, this is a browser limitation (usage of port 6667 is restricted). You'll need to pick another port to use.
