Firefox WebExtensions tabs.onUpdated incorrect argument

I'm creating a simple webExtension for firefox and I want to use tabs.onUpdated with a filter. I copied an example from mozilla site:

const pattern1 = "https://developer.mozilla.org/*";
const pattern2 = "https://twitter.com/mozdevnet";

const filter = {
  urls: [pattern1, pattern2]
}
function handleUpdated(tabId, changeInfo, tabInfo) {
  console.log(`Updated tab: ${tabId}`);
  console.log("Changed attributes: ", changeInfo);
  console.log("New tab Info: ", tabInfo);
}
browser.tabs.onUpdated.addListener(handleUpdated, filter);

When I reload my extension I get this error in console:

Error: Incorrect argument types for tabs.onUpdated.  background-script.js:14:1
  makeError resource://gre/modules/Schemas.jsm:446:14
  throwError resource://gre/modules/Schemas.jsm:2138:11
  checkParameters resource://gre/modules/Schemas.jsm:2195:7
  addStub resource://gre/modules/Schemas.jsm:2381:21
  <anonymous> moz-extension://78d98d27-294e-4774-9461-dfb3dda97871/background-script.js:14:1

I don't know if there was some changes in this api which wasn't documented yet or there is some other problem, maybe with permissions.

These are my permissions from manifest.json:

"permissions": ["activeTab", "notifications", "tabs"]

extraParameters is supported from Firefox 61 onwards: https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/tabs/onUpdated

If you want to support an older version, you should use an "if" statement in your onUpdated listener.
