1.4 is the final release. Sourcecode to be released. I sincerly hope someone continues this project. For those who don't know, MozBackup
is a utility for backing up and restoring Mozilla (Firefox/Thunderbird) profiles. It is the ONLY way in my opinion to fully port your Thunderbird settings and mail from one machine to another. If you have ever tried to do this manually, especially from one OS to a different OS - even a Windows box to another Windows box - it is an extreme pain.
With MozBackup it litterally takes seconds to port Thunderbird e-mail and account settings from one box to another.
