                    should be allowed
           Product: WebKit

          Hardware: Mac (Apple Silicon)
                OS: macOS 13
            Status: NEW

I'm trying to build a "Responsive Viewer" extension for Safari with a Safari Web Extension.

The extension loads a page into an iframe so that the user can resize and check how the page is responsive.

Some websites won't load in iframes.

In Chrome, I can use declarativeNetRequest to modify the response headers and remove the "frame-options" header that blocks the page from being loaded into an iframe.

Loading the page into an iframe is the only way a "Responsive Viewer" extension could work.

The extension already has all the permissions it needs from the user, and declarativeNetRequest is the safest way.

Please let extensions modify headers from the response as well.
