You didn’t reply to or contradict anything they said. You need Xcode to build extensions and Safari has a super limited API. Executing JS and CSS don’t address either.

He didn’t say limited, he said nonexistent.

More specifically, if you can inject scripts I don’t see why you couldn’t call window.close()
