How to block a URL in Chrome's developer tools network monitor

Question

I am currently analysing my page connections and I want to block some tracking scripts and other external URL calls in my network monitor inside Chrome\'s developer tools.

Answer 1

As pointed out by @calavera.info, @iman.Bahrampour, and @Asim K T this feature is now available in Chrome 59. You can select a URL or domain to block in the Network panel. See this release note and these Screenshots where the StackOverflow logo has been blocked from this page. @iman.Bahrampour also shares two extensions below that will also do this ("HTTP Request Blocker" and "Request Blocker").
