chrome.webRequest.onBeforeRequest listener won't fire on some websites

Question

I have a chrome extension,

I am trying to catch webRequest for example onBeforeRequest, but it doesn't fire on some web requests. Is it even possible to not have a onBeforeRequest fired on some http or https website? or I am confusing the url patterns somewhere?

This is the code in background.js. beforeRequest is never executed on some websites. Not if I try on this website for example: https://discourse.mozilla.org/t/onbeforerequest-event-not-fired-firefox-is-started-with-command-line-options/33557

Is it possible that url patterns

"<all_urls>" or "*://*/*" don't match with the URL?

chrome.webRequest.onBeforeRequest.addListener(
function(details){
    beforeRequest(details.tabId);
  }, {urls: ["<all_urls>"],types: ["main_frame"]}, [ "blocking" ]);

This is the manifest.json
