Rated 5 out of 5 stars

I just successfully installed the latest version from https://addons.mozilla.org/es-ES/firefox/downloads/file/83890/equake_alert-4.3.3.6-fx.xpi?confirmed, which hvillanu (see below) was kind enough to post. It's version 4.3.3.6.
Now all is better and I can see what's shaking again. My thanks to the developer for creating a 'must have' add-on.

This review is for a previous version of the add-on (4.3.3.6).
