Popups, overlays, click-hijacking, redirects. The aggressive stuff that slips through. IronCurtain stops it before it reaches your screen.
Blocks window.open calls to ad URLs and known ad network domains at the script level.
Detects and removes fixed-position overlays, interstitials, and transparent click-hijacking layers in real time.
Blocks requests to 25+ ad domains before they load using Chrome's declarativeNetRequest API. Zero performance overhead.
Automatically removes scroll locks when sites freeze your page with overflow:hidden or position:fixed on body.
Blocks navigation hijacking via location.assign, location.replace, and history.pushState to ad URLs.
Intercepts ad library calls (aclib, popunder scripts) and blocks ad script injection via createElement.
Blocks requests to known ad domains before they load. Uses Chrome's built-in declarativeNetRequest API so there's zero impact on page speed.
Runs in the page's own JavaScript context to intercept the actual API calls that trigger popups, pop-unders, and redirects. Blocks them at the source.
Detects and removes overlay elements in real time using heuristic analysis. If a site locks your scroll, IronCurtain restores it automatically.
