Is Popup Blocker - block pop up requests safe?
Popup Blocker injects a hidden, id-tagged element into every page it runs on, letting any site detect that it's installed.
On every page you visit, the extension's content script appends an empty div to the page whose id is built from part of the extension's own identifier. Because this happens on all sites and the id is predictable, any website's own script can check for that element to learn you have this extension installed. The element itself carries no visible content or additional data beyond marking the extension's presence.
