Works well Rated 5 out of 5 stars
It has been working well for me on Mac OS X. The only thing I miss is a setting to have the notification visible always. A crude workaround is that I configured Growl to show all notifications from Firefox to be "Always" visible. Not the ideal solution, but I currently don't have any other notifications coming from Firefox, so should work fine for now.This review is for a previous version of the add-on (1.9.1-signed).
