Title: [fix bug 904042] Background fade display bug on IE8 Firefox os page

This should fix the IE8 background image bug described here: https://bugzilla.mozilla.org/show_bug.cgi?id=904042

I also noticed that adding a slight (100ms) delay to the phone screen transition in the top section helps make for a smoother animation on older browsers, so I added that to this PR.
