title: Create Internet Explorer extension changing content of a webpage
body: <p>I'd like to develop an Internet Explorer extension that changes the content of a specific webpage, like content scripts in Google Chrome. (eg. when I go to the website Google and I search for "car" I'd like to have a div created on the page with the word "car" inside).</p>
  
  <p>I've been looking on SO but haven't found clear evidences if this kind of thing is possible.</p>
  
  <p>What I'm specifically looking for is a clear tutorial or some example of how to do this.</p>
