title: puppeteer unable to load chrome extension in browser
body: <p>This is my first time using puppeteer and I want to open a google chrome page and navigate to a chrome extension I have installed . I try to enable the chrome extension but when I run my script in <code>headless:false</code> mode the browser pops up without my extension .</p>
  <p>My code :</p>
  <pre><code>//my extension path 
  const StayFocusd = 'C:\\Users\\vasilis\\AppData\\Local\\Google\\Chrome\\User Data\\Default\\Extensions\\laankejkbhbdhmipfmgcngdelahlfoji\\1.6.0_0';
  
  async function run(){
    
    //this is where I try to enable my extension 
    const browser = await puppeteer.launch({
      headless: false,
      ignoreDefaultArgs: [`--disable-extensions-except=${StayFocusd}`,&quot;--enable-automation&quot;],
    } 
  
    );
    
    const page = await browser.newPage();       
    sleep(3000);
  
    await browser.close();  
  }
  
  
  run();
  </code></pre>
  <p>So the extension does not load and I get no error or anything . I would appreciate your help</p>
