title: Chrome Extension : How to Get a form and fill and submit it
body: <p>I am building a chrome extension where I need to get HTML from the website. It has a form which needs to be filled and submitted back.</p>
  
  <p>I click the extension button, pop up opens. I enter details. It fetches me a website which has a form that needs to be filled and submitted back.
  I currently am using tabs to open the URL, fill the form and submit it back, but I dont want the user to see all the happenings.</p>
  
  <p>I also tried Ajax but not sure how exactly to get HTML, fill the inputs and submit it back.</p>
  
  <p>I tried iFrames but then I get the Unsafe javascript error.
  Not sure I want to use background page as it will be running in the background always.</p>
  
  <p>Is there any way I can actually make it happen in the background?</p>
  
  <p>Thank You</p>
