title: Popup HTML to last viewed page
body: <p>I am making an Chrome extension. I'm not an coding expert, but I understand the basics of html, css, and how to make an chrome extension.</p>
  <p>I have an popup html, and I want to reference to other html pages, but every link will open in a new tab. I searched all over the internet, but I couldn't figure out how. When the popup is open on another page, and it closes, I want it to open on the same page. Is there an way, and how?</p>
  <p>Thanks in advance.</p>
