Description:
Detects likely third-party single points of failure as you browse and allows you to Simulate 3rd party resources being unavailable so you can see what the impact would be on sites.
To enable content blocking, click the greyed-out black hole icon in the toolbar.
As you browse the icon in the toolbar will display a warning icon if you are on a site that is likely to have problems loading third-party content. If you click on the icon it will display the list of suspect resources as well as how much of the page content they block (resources closer to the top of the page will have more of a user impact).
Note: SPOF-O-Matic will re-request the pages you browse in order to get the original HTML to scan for blocking scripts so you may see duplicate requests for the base page in tools like fiddler or wireshark.
