When I left Firefox there weren't even any pages loaded - (just about:home)

This will cause unnecessary battery drain.

So why does Firefox use so many CPU cycles for about:home, is it running javascript for a page I closed? (wired.com)

Hi, I've also noticed Firefox v27 (updated Feb 2014) is using 25% cpu on android v4.1.2 on a galaxy s2. I have no addons installed. Im on a rooted phone and can run the linux 'top' command. Firefox doesn't appear to exit properly when I press the home key and it sits on it's home screen flattening the phones battery all day long.
