Rated 5 out of 5 stars
I used the original keyconfig for years and am very pleased to have this new and maintained version on AMO now. So many more Firefox and Thunderbird users can find this helpful tool.
Maybe the developer wants to add this forum http://forums.mozillazine.org/viewtopic.php?f=48&t=72994 to this AMO page. In this forum users get and give help to add own shortcuts.
