 > ma1: are you aware of this one?

 Of course I am, see
 https://github.com/hackademix/noscript/blob/11.0.9/src/lib/SyncMessage.js#L3

 Even though this is innocuous ( https://en.wikipedia.org/wiki/.invalid ),
 it shouldn't normally happen, because those requests are intercepted by
 our webRequest listener and redirected to a data: URL before (pointless)
 DNS resolution attempts. I suppose a content script is triggering the
 request before the listener is ready to answer, or we're watching
 speculative resolution.

 Regarding "connections to 255.255.255.255", did you actually see any?
