Source code for "Ignore X-Frame headers" chrome extension; see https://chrome.google.com/webstore/detail/ignore-x-frame-headers/gleekbfjekiniecknbkamfmkohkpodhe

background.js

chrome.webRequest.onHeadersReceived.addListener(
  function (details) {
    return {
      responseHeaders: details.responseHeaders.filter(function(header) {
        return (header.name.toLowerCase() !== 'x-frame-options');
      })
    };
  }, {
    urls: ["<all_urls>"]
  }, ["blocking", "responseHeaders"]);

manifest.json

{
   "background": {
      "scripts": [ "background.js" ]
   },
   "description": "Drops X-Frame-Options HTTP response headers, allowing all pages to be iframed.",

   "update_url": "http://clients2.google.com/service/update2/crx",
   "version": "1.0"
}

Heads up there's a formatting error. "\u0003Call_urls" should be "<all_urls>"

Hi Can i get a suggestion as how to use this into my code?

This used to work but not anymore. Could it be that Chrome changed their security policy or API?

Recommendations as the "Ignore X-Frame headers" Chrome extension author:

• Do not use the source code above because it is out-of-date e.g. misses fixes for Chrome permission changes.
• Instead, use the official, up-to-date source code repository linked in the extension page: https://github.com/guilryder/chrome-extensions/tree/main/xframe_ignore
