title: Mozilla FF browser.tabs.create() doesn't work
body: <p>I have a problem with my own extension for mozilla firefox. I want to open a new tab after click event on a document. I wrote this:</p>
  
  <pre><code>  (() =&gt; {
      document.addEventListener('click', () =&gt; {
        console.log('click');
        browser.tabs.create({});
      });
    })();
  </code></pre>
  
  <p>What is wrong with my code? Console prints'click' so event works. Also in manifest.json I have this permission (and only this one):</p>
  
  <pre><code>"permissions": [
      "tabs"
    ]
  </code></pre>
  
  <p>I will be very gratefull for an answear :)</p>
