I have been using and sending support to T-Bird for 20+ years. I used to use mozbackup to backup and or move my installation. However, I am not sure it works with the newer version(s) of T-Bird and I do not want to mess up my installation.

Please create a backup utility so I can archive my installation and emails so it can be moved in total to a new or another computer seamlessly.

Thank you!

Do not use mozbackup. Even the author recommends on website to not use. The safest backup is this; - exit thunderbird - copy c:\users\<yourid>\appdata\roaming\thunderbird to external drive to restore: - exit thunderbird, if running - copy the backed up thunderbird folder to c:\users\<yourid>\appdata\roaming to overwrite the existing thunderbird folder. This works 100%. My suggestion here refers to Windows, but would be similar to other OSs.

If the profile is smaller than 2 GB, use Tools/Export... Tools/Import... to import.
