title: Start firefox and close after few minutes with batch file
body: <p>i have a small script that starts waits 60 seconds,starts firefox and runs a imacros script
  but the problem is i want to close firefox after 60 seconds and start it again through loop.But what this script does is .It waits for me to close firefox.Then starts 60 seconds timer and then loops the script.</p>
  
  <p>What i want to do is .It should not wait for me to close firefox and directly force closes firefox after 60 seconds and runs in loop</p>
  
  <pre><code>  @Echo off
  :loop
  cls
  taskkill /f /im Firefox.exe
  cls
  taskkill /f /im crashreporter.exe
  cls
  timeout /T 60
      start "" 
  "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" imacros://run/?m=l4lyt.iim   
  timeout /T 60
  goto loop
  </code></pre>
  
  <p>What am i doing wrong?why does it waits for me to close firefox instead of directly going to next line.
  i.e</p>
  
  <blockquote>
    <p>timeout /T 60</p>
  </blockquote>
