Rated 4 out of 5 stars
I'd give this five stars if I hadn't had to wait so long for the update. It's been several months and several Firefox versions ago since I was able to use it.
I never thought I'd get so into earthquakes, and can't remember why I downloaded it to begin with, but now that I've used it, I REALLY MISS IT!! Please update!!!
