title: Can I pass a JavaScript variable to another browser window?
body: <p>I have a page which spawns a popup browser window. I have a JavaScript variable in the parent browser window and I would like to pass it to the popped-up browser window.</p>
  
  <p>Is there a way to do this? I know this can be done across frames in the same browser window but I'm not sure if it can be done across browser windows.</p>
