In the latest move to improve the privacy of the Chrome browser, Google is adding support for a new HTML tag that prevents user tracking by isolating embedded content from the page embedding it.
To prevent this, Google is adding a new form of embedded iframe called a "Fenced frame" to isolate the embedded content and not allow it to see the user data of the embedding page.
Fenced Frames are a new form of an embedded document, and it "Forces a boundary between the embedding page and the cross-site embedded document." This change ensures that two sites cannot share your data, which would help prevent user tracking or other privacy threats.
They're not allowed to communicate with the embedder and vice-versa, except for certain information such as limited size information, the embedder's top-level site, and the frame's document url.
Google Chrome status page for this feature states that fenced frames are still a prototype and are not in active development.
Its recent addition to test builds shows that Google plans on bringing this feature to the Chrome browser in the future.
