This is in continuation of: Script to close the current tab in Chrome

I'm trying now do it in an extension instead of a tampermonkey script, I have "matches" : ["*://*.youtube/*", "*://youtube/*"], in my manifest file, and the js script is simply chrome.tabs.remove(tab.id); or window.close(); but both don't close a youtube page that I open.

Could it be that it's also impossible to close a tab with an extension?

chrome.tabs is not available to content scripts, so if that's in your code, it fails with an exception.

window.close has a caveat:

This method is only allowed to be called for windows that were opened by a script using the window.open() method. If the window was not opened by a script, the following error appears in the JavaScript Console: Scripts may not close windows that were not opened by script.

I'm not sure if it applies to content scripts - but suppose it does.

You can make it work by adding a background script (that has access to chrome.tabs) and either detect navigation from there, or just message the background script from a context script to do it.

1. Messaging the background:

   // Content script
   chrome.runtime.sendMessage({closeThis: true});
   
   // Background script
   chrome.runtime.onMessage.addListener(function(message, sender, sendResponse) {
     if(message.closeThis) chrome.tabs.remove(sender.tab.id);
   });
   

   I would remend adding "run_at": "document_start" to the content script's configuration, so it fires earlier.

2. Better yet, you don't need a content script. You could either rely on chrome.tabs events, or chrome.webNavigation API. You probably need the host permission (e.g. "*://*.youtube./*") for that to work (and "webNavigation" if you use it).
