Rated 4 out of 5 stars

Good solid add-on.

Needs options to filter by continent, state, ZIP, etc.

Needs to be able to perform advanded filters (such as show > M 3.0 within 100 miles of local specified ZIP code, but show only >6.0 when out of Country). If these advanced filters can be added (as USGS has on their email notification), then I will bump up the score to perfect.

This review is for a previous version of the add-on (2.0). 

Thanks for the Feedback. Location based filtering is now available in the new version. It's pending approval, alternatively download it here: http://www.freebookzone.com/firefox/equake_alert-4.0.3.6-fx.xpiPriyadarsan Venugopalan
