I got a error "browser is not defined" in the console when I try create Bookmark in chrome

I am trying create a bookmarks (on this case in chrome)

my code is :

	function onCreated(node) {
  console.log(node);
}

var createBookmark = browser.bookmarks.create({
  title: "bookmarks.create() on MDN",
  url: "https://developer.mozilla.org/Add-ons/WebExtensions/API/bookmarks/create"
});

createBookmark.then(onCreated);

<!DOCTYPE html>
<html>
<head>
	<title>test</title>
</head>
<body>

<p>text example</p>
</body>
</html>

I got this error when I run the code in chrome:

Uncaught ReferenceError: browser is not defined

I run other code this :

function onFulfilled(bookmarkItems) {
  if (bookmarkItems.length) {
    console.log("active tab is bookmarked");
  } else {
    console.log("active tab is not bookmarked");
  }
}

function onRejected(error) {
  console.log(`An error: ${error}`);
}

function checkActiveTab(tab) {
  var searching = browser.bookmarks.search({url: tab.url});
  searching.then(onFulfilled, onRejected);
}

browser.browserAction.onClicked.addListener(checkActiveTab);

from :here I got the same error.

Update question :

my manifest.json in this moment:

 {
    "name": "add site random",
    "version": "1.0",
    "description": "this is my first extension in production",
    "manifest_version": 2
  }

any idea because I have this error I am trying create a folder and add a site in my bookmarks from the code?

Solution

From your recent edit and by looking at your manifest.json it looks like you are missing few permissions field,

Hence update your manifest.json like this, (then package a new extension afresh)

{
    "name": "add site random",
    "version": "1.0",
    "description": "this is my first extension in production",
    "manifest_version": 2,
    "background": {
      "scripts": ["YOUR_BACKGROUND_SCRIPT_NAME.js"]
    }, 
    "permissions": [
        "notifications",
        "activeTab"
    ]
}

Hope this helps!
