Rated 5 out of 5 stars
As someone who loves knowing what's going down with Mother Earth's seismic activity, this extension was a Goddess-sent little doodad!
But...I just upgraded to the new version of FF, so it's not compatible...boo!
Of all the extensions I've ever considered donating to financially, this is one of the first--and the most helpful if you're into knowing where an earthquake hits before the media do! ;)
