umatrix is the layer7 firewall you're looking for, it can block websocket connections, cross-domain ones in particular are quite easy.
- djsumdog 6y agoI've had performance issues with umatrix. I tried blocking all JS by default and explicitly enabling scripts. In theory that should make the browser preform better. I suspect there are a bunch of sites that can't run a function or reach a JS resource and then just go into spin loops eating through resources .. either that or the blocking itself is resource intensive.
- the8472 6y agoblocking has non-zero cost, yes. especially if complex whitelists need to be evaluated for every request. but at least for me it still is a net win most of the time. But you can also operate umatrix in a blacklist-based approach, i.e. simply let most requests through except the categories you deem problematic (e.g. cross-site websockets in this case)
