title: How to make a chrome plugin
body: <p>I was curious how to make a chrome plugin that loads some JS on every page - I've seen it done before, but now I want to make my first chrome plugin, one that changes all the fonts on websites to comic sans ms. Yep, this is a prank to pull on friends computers.</p>
  
  <p>I would assume it would take like 4 lines?</p>
