title: Selenium: How to wait for options in a select to be populated?
body: <p>I am using Selenium for the first time and am overwhelmed by the options. I am using the IDE in Firefox.</p>
  
  <p>When my page loads, it subsequently fetches values via an JSONP request, with which it populates options in a select.</p>
  
  <p>How do I get Selenium to wait for a certain option in the select to be present before proceeding?</p>
