This Is Being Fixed! Rated 2 out of 5 stars

I had emailed the person that maintains this plug-in, and I got this in response to my email today.

I have just submitted a fix for this to Mozilla today. It should be live in the next couple days

Hopefully, we'll all be up & running again in just a few days! :D

This review is for a previous version of the add-on (1.3.3.1-signed.1-signed).
