Use a Debian or Ubuntu Thunderbird 1.0 package. I've backported Thunderbird 1.0 to Warty. See : http://ubuntuforums.org/showthread.php?t=8486 Add the repositories as instructed. Then, *apt-get update; apt-get install mozilla-thunderbird* NOTE: Backports is not an official Ubuntu project, no warrantee, implied or otherwise.... you get the point. -- jdong
