title: Chrome Extension on Facebook with Dynamic Posts
body: <p>Sorry, I think this post probably exists but I couldn't find it. Maybe I am using the wrong words.</p>
  
  <p>I am making a Chrome extension that looks at Facebook posts and does something to them. My Content Scripts gets the posts correctly, but the new ones that are generated as the user scrolls down are not captured since they came later. I tried hooking into an ajaxComplete handler, but that didn't work (<a href="https://stackoverflow.com/questions/17986020/chrome-extension-javascript-to-detect-dynamically-loaded-content">Chrome-extension Javascript to detect dynamically-loaded content</a>) I am not sure if I did something wrong or if this isn't what I want. </p>
  
  <p>So, how can I detect these new posts and change the contents of them before the user notices? Any tips are appreciated.</p>
  
  <p>Thanks!</p>
