Allow blocking or whitelisting web sockets

[briannelsonutd]

ebay is using javascript and the localhost IP address to scan Windows systems locally. No web page code should be able to perform this.

Firefox I believe network.websocket.enabled = false disables this functionality
Do you set this as a browser wide default? Creating a whitelist to allow your bank or other trusted entity to scan for malware might be acceptable. But once you get to that level, uMatrix or other plugin provides that functionality.

I am interested to see your perspective.
