dns lookup for noscript-csp.invalid

Post by guest »

I just did some dns query logging and spotted the entry noscript-csp.invalid. I don't remember ever seeing it there before. Is this normal and intentional?

Yes.
*Always* check the changelogs BEFORE updating that important software!

Specifically, the requests are used locally for content activation detection and blocked before they reach the net, but some DNS queries (resulting in an invalid response) may be escaping before of speculative resolution by the browser.
