Note on X-Frame-Options

Some major websites (like Google, Facebook, Twitter) prevent themselves from being displayed in iframes for security reasons (X-Frame-Options policy).

If a site shows a blank white screen or "Refused to connect", it likely has this protection. Drag and drop a local HTML file or test with your own development sites!
