Profile from Thunderbird ver 91.xx from Ubuntu 22.04 cannot be imported into Thunderbird ver 102.15.0 bundled with Ubuntu 23.04. I have several copies of the pre-existing default profile.

Saved profiles are on thumbdrives formatted with linux Ext3/ext4 file system.

I have not successfully imported the profile from Tbird v91.xx to the new install of Tbird v102.15.

I have tried with the profile manager, opened from the command line with Thunderbird closed.

I have also simply copied the profile folder and renamed to existing default profile in new OS install that included Tbird v102.15.0.

I am thinking that if I installed a previous version of Tbird, my old profile might live again, but I have not found earlier versions of Thunderbird on the download page. I have a bunch of data in the old profile I would like to keep.

Any suggestions?

Bang Zoom Whoosh! I fingered it out -

Should anyone else find themselves in this situation;

The profile in Thunderbird v102.15.0 has a slightly different name than what I found in the previous version (v91.xx - I think). The dot Thunderbird directory ( Home/.thunderbird) contains two dirs that look like profile dirs.

  • xxxxxxxx.default
  • xxxxxxxx.default-release

The profile dir I copied from the previous Thunderbird version is named like the first example. The profile dir that seems to be active in Thunderbird v102.15.0 is the second.

When I renamed the existing xxxxxxxx.default-release to xxxxxxxx.default-release_renamed, and then renamed my copied previous profile to xxxxxxxx.default-release,

I got all misty seeing all my data come back to life.

Hope this helps.
