title: Is it possible to have two separate chrome.onHistoryStateUpdated Functions
body: <p>This is currently the code that I have, which injects my custom stylesheet into a specific website when the history state gets updated (in my background.js):</p>
  <pre><code>chrome.webNavigation.onHistoryStateUpdated.addListener(function(details) {
    chrome.tabs.insertCSS(null,{file:&quot;results.css&quot;});
  
  })
  </code></pre>
  <p>I want to add another listener similar to this in order to inject another one of my stylesheets into a different website when the history state is changed again. But I don't know if this is possible, and if it is, how to specifically call that second listener. Do I have to send a message from my content.js?</p>
  <p>How can this be resolved?</p>
  <p>Thanks!</p>
