Works fine in my Firefox 15.0 Rated 5 out of 5 stars

For those with non-working installations, have you disabled other add-ins one by one to check for an interfering add-in? I have quite few add-ins installed, but only enabled when I need to use them to avoid add-in incompatibilities.

This review is for a previous version of the add-on (1.5.1.1.1-signed.1-signed).  This user has a previous review of this add-on.
