Extension summary
See how your page loads when 3rd party JavaScript fails to load.
Example 3rd party scripts are those you include for social buttons like Facebook Like, Twitter, Google+ etc
Including these external JavaScripts in a blocking manner is a SPOF (Single Point Of Failure) for your site. This means an outage. You should always load these asynchronously.
Sites do go down. Even big ones. Or they fail to load for other reasons (e.g. corporate firewall blocking). You don't want your site to go down when a third party goes down.
// You want: your outage = your outage
// as opposed to you outage += Google outage + FB outage + Twitter outage + LinkedIn + .....
This extension helps you visualize the negative effects by redirecting recognized third party JavaScripts to a blackhole (http://blackhole.webpagetest.org).
