Rated 4 out of 5 stars

This is a very nice extension to Firefox, but I would suggest an improvement: a filter of countries, so that we can choose the places from which we want to receive earthquake information. Because I live in Portugal and I don't care about earthquakes in other places, but would really like to know up-to-date information about the activity in my country, or others of my choice. Other nice improvement would be maps with the locations of recent earthquakes, much like the 'Radar' option in ForecastFox.

This review is for a previous version of the add-on (3.0.1).
