Single Origin

Restrict loading resources from the origin domain, and chosen other domains

Prevent the browser from loading resources from domains other than those you visit and any exceptions you choose. This is different to other extensions which have a long list of disallowed domains - every cross domain request is blocked until explicitly permitted With this extension when each page is loaded it can only load resources (Javascript, images, css, frames, etc) from the same domain (subdomains are permitted). Resources can be permitted from other domains using the popup on the icon in the browser toolbar. If a frame is loaded from another domain then permissions can be set for that domain separately. The extension can also be set to allow all resources for a tab using the popup.
