The layout in Link Detox Screener may look broken because it uses a sandboxed iframe to load pages. This is done to protect you from potentially malicious sites, and to prevent them from accessing sensitive data like cookies, local storage, and session storage.
However, some sites do not allow resources like fonts, CSS, images, or JavaScript to be loaded from sandboxed iframes. In these cases, the layout of the page may be broken, and some elements may not be displayed correctly.
This is not a cause for concern, as the sandboxed environment used by Link Detox Screener ensures that malicious sites cannot access your sensitive data. You can continue to use the tool safely, and be confident that your data is protected.
