This Firefox warning kind a made me uncomfortable and I end up removing it. Would reinstall if this is taken care of.

Nice simple extension. Three things on my wishlist: Slightly darker color. Hard to see on my older laptops. Time modification. I'd like to be able to control how long before refresh. Countdown indicator? Some kind of movement on the icon - time or any kind of indicator.
