On a recent Firefox (31.5), the page remains white if it is opened in background, but loads fine in the tab in which I open it has the focus.

  Yes. That is because I pause the rendering engine if the browser tab is not focused. I don't want to consume a bunch of CPU and memory when the user isn't looking at the site.

    the issue is that it never starts rendering, even once the tab is focused.
