Hrm. I'm more familiar on how to open it in Chrome, but you should be able to open a developer console that monitors the page as it loads and reports any errors.

User-js loads last, so it's possible that your page loads are just timing out before it gets loaded, and it's also possible that some other error is causing it not to load.
