I've looked at Firebird, but I'm sticking with Mozilla 1.5 until Firebird and Thunderbird mature a little; even so, I hope I might be of limited help. I'm not sure if this is what you need or not, but the only Firebird directly I'm familiar with is found in: /<your home directory>/Library/Phoenix/ (Phoenix was the previous name of Firebird.) Be careful deleting that directory, though, because your bookmarks and other personal data are stored there. If you delete it, you might want to back it up first. The installation notes may also mean that you should delete the old Firebird application instead of overwriting it. But that's just a guess on my part. Hope this helps, Mike W.
