No X-Frame-Options

sklab

Overview: This extension enables you to display external websites using embedded tags on your personal dashboard or digital signage. Details: When displaying another HTML page inside an HTML embedded tag (<iframe> or <embed>), another HTML page may not be displayed. The reason for not displaying the page is that the accessing server is responds with response headers ("X-Frame-Options", "Content-Security-Policy") to deny the display. This extension can remove these response headers. Notes: It's a security risk to turn ON this extension all the time. Only turn ON this extension when necessary.
