title: How to read reviews from google chrome webstore?
body: <p>I have a chrome extension in the webstore. I would like to read the reviews against my extension from my extension . I tried injecting a .js page into my extension's review page but I get the error "Tab was closed".
  Here is my code:</p>
  
  <pre><code>var popup=window.open("https://chrome.google.com/webstore/detail/convergehub-lead-generato/mjcffemmfdpcjekgonelgmphacdhhbod/reviews");
  chrome.tabs.getSelected( null, function( tab ) {
    chrome.tabs.executeScript( tab.id, { file: "./lib/reviews.js", runAt: "document_end" }, function() {
      if (chrome.runtime.lastError) {
        alert(chrome.runtime.lastError.message);
      }
    });
  });
  </code></pre>
  
  <p>In my reviews.js there is only 1 line 
  alert("here"); </p>
  
  <p>In the above code I always get the alert "Tab was closed". Is there any other way to get the reviews ? Am I doing something wrong here ? Is this even allowed on the webstore page ?</p>
