In Firefox iOS we need our custom URL scheme to perform HTTP 3xx redirection.
This webkit bug https://bugs.webkit.org/show_bug.cgi?id=173730 indicates that support for this was fixed in WebKit.

Steps to Reproduce:

With a custom URL scheme installed, use the following response in the WKURLSchemeHandler, which should redirect to google.com.

func webView(_ webView: WKWebView, start urlSchemeTask: WKURLSchemeTask) {
     let resp = HTTPURLResponse(url: urlSchemeTask.request.url!, statusCode: 301, httpVersion: "HTTP/1.1", headerFields: ["Location": "https://www.google.com"])!
      urlSchemeTask.didReceive(resp)
      urlSchemeTask.didFinish()
}

Expected Results:

Perform HTTP redirection to google.com

Actual Results:

Nothing happens
