What do you mean by "nothing is shown"? Doing a screenshot of the thunderbird folder may help. Also, clicking help>troubleshootinginformation, selecting 'profile folder' and clicking 'open folder' may help to verify the profile's location. I am a novice with Linux, but I am aware that distributions may store profile in different locations.

Thanks for the reply. Usually when I transfer the Thunderbird profile folder, I then open Thunderbird and find all my accounts, address book, etc in place.

When clicking help>troubleshooting information, selecting 'profile folder' and clicking 'open folder' I can see the profile folder inside the Thunderbird folder as I would expect.

I do not use Linux at all. However, I know that Thunderbird needs to be pointed to a given profile folder for it to see it. On Windows, that happens in the profiles.ini file. I believe this can also be set by starting the Thunderbird Profile Manager. Perhaps there is something there that will help.

That is also true in Linux. I suggest you browse the profiles.ini to see what profile it is pointing to.

Still no luck. But I have realized that while everything is kept in a folder called 'Thunderbird' on Windows, the corresponding folder on Linux Mint is called '.thunderbird'.

So I have copied the contents of the Thunderbird folder into the .thunderbird folder on the Linux computer.

As far as I can understand, the profiles.ini file is pointing to the profile that I want to use.

[InstallD78BF5DD33499EC2] Default=Profiles/r8iev7tw.default

[Profile1] Name=default-esr IsRelative=1 Path=c8pbep7v.default-esr

[Profile0] Name=default IsRelative=1 Path=Profiles/r8iev7tw.default Default=1

[General] StartWithLastProfile=1 Version=2

[InstallFDC34C9F024745EB] Default=c8pbep7v.default-esr Locked=1

If I look at the Profile Directory in Thunderbird, it is shown as 'c8pbep7v.default' So why isn't it working?

Success! I didn't know how to set the default profile until I read this:

Recent versions of Thunderbird and Firefox have a about:profiles link in Help -> Troubleshooting Information. Clicking on that link launches an enhanced version of the profile manager.

Once that opened I clicked on the button to set r8iev7tw.default as default profile.

Thanks to all who have replied to this topic.
