Single Origin is a free Chrome extension developed by dwbinns in the Browsers category. It falls under the Add-ons & Tools subcategory. This extension offers a unique approach to blocking cross-domain requests by preventing the browser from loading resources from domains other than the one you are currently visiting, with the ability to add exceptions.

Unlike other extensions that have a long list of disallowed domains, Single Origin blocks every cross-domain request by default. This means that when a page is loaded, it can only load resources such as JavaScript, images, CSS, frames, etc. from the same domain (subdomains are permitted). However, the extension provides a convenient popup on the browser toolbar icon where you can permit resources from other domains for the current page.

If a frame is loaded from another domain, you can set separate permissions for that specific domain. Additionally, the extension allows you to easily allow all resources for a tab using the popup.

Single Origin is a powerful tool for users who want to have more control over the resources loaded by their browser. By restricting the loading of resources from other domains, it helps enhance security and privacy while browsing the web.
