Latest code works Rated 5 out of 5 stars
Looks like the version published here is broken for FF < 4. As suggested I was able to get it working using the latest code in github. I couldn't find a package for 1.6.3, does anyone know the URL for it?This review is for a previous version of the add-on (18.104.22.168-signed).
1.6.3 is now reviewed and available.
