Can't see video controls

I recently updated Divx and Firefox, and all of a sudden I can't see anything except the video when I use Divx WebPlayer. No play button, pause button, track, volume...nothing. Just the video. I've uninstalled, reinstalled, uninstalled again, installed an older version, uninstalled firefox and reinstalled it...I'm thinking maybe it's a setting, but I don't know how to change it.
