title: When click a <a> link in chrome extension, how can popup.html keep open state?
body: <p>I'm doing a Chrome extension about looking though posts from a forum.</p>
  
  <p>Now,I can get some posts' links and I put these links into  in my popup.html like this:</p>
  
  <pre><code>&lt;a href="post's link" target="_blank"&gt;post's title&lt;/a&gt;
  </code></pre>
  
  <p>Then when I click the  link, a new tab will be opened, but the popup.html page will disappear.</p>
  
  <p>And when I click with pressing , new tab will be opened, but problem still exists.</p>
  
  <p>Now, I want to know if I can open a new tab by clicking a  link, and in the meantime I can keep my popup.html page still Show.</p>
  
  <p>I refer to the documentation of chrome extension development, but I still can not solve this problem.</p>
  
  <p>So, can this be realized? And how?</p>
  
  <p>Thanks!</p>
