and also the whole adress list is gone away. /Lasse

probably this https://thunderbirdtweaks.blogspot.com/2019/09/i-lost-my-profilemail-on-update-to.html

Hellow Matt and thank You for Your quick answer. I will try to follow your recommendation to solve the problem. However I want to know which version of Thunderbird should I have men I try to make the changing. version 60.0 (the version which contains my adress list) or version 68.10.0 (the version where I lost my adress list) best regards 7 Lasse

Use version 68.10.0

It is likely Thunderbird has created a new profile, so see if you can reselect the correct one.

• Help > Troubleshooting Information

Under 'Application Basics' section, at the bottom you will see 'Profiles' and next to it in right column

• 'about:profiles'.
• click on 'about:profiles' and it will open in a tab.

It will list the profiles.

Each profile has a name and the new one is probably called 'default release'. So you will see:

• Profile: default release
• Profile: default

Each profile will say:

• Default Profile: yes or no
• Root directory
• Local Directory

The current default profile will have a 'rename' button below it. I think profile: default release may be the current profile.

The other profile which could be your old profile - not currently set as default - will have additional buttons below.

• click on 'Set as default profile'

• Exit Thunderbird

Wait a few moments for background processes to complete, then start Thunderbird and report back on whether it works.

Report back on whether it works. If it is still not showing contents, then there is a possible bug to do with the Global Database. In which case follow the instructions at the following link to rebuild the Global Database.

Hello Toad Hall There were 4 profiles.. Default, Default- release, Default-release-1 and Default-release-2 where the second was "yes" and the other "no" I set Default-release-1 to default profile but after restarting Thunderbird no change (no maps or adress list). I made a new chage and set Default as default and (BINGO) now all local maps and the adress lists were back again. Now how should I continue? Should I delete the profiles I am not using and which seems not working? Default-release, Default-release-1, and Default-release-2?

best regars and thousend thanks / Lasse

It's worth keeping 'default-release' - just in case. But the others, Default-release-1 and Default-release-2, I would delete.

Exit Thunderbird first before deleting those two profile names from the 'Profiles' folder.

Could you mark my first comment as a 'Chosen solution' so that others with similar issue will find it easier to locate. Cheers.

Hello again Toad-Hall You wrote "Exit Thunderbird first before deleting those two profile names from the 'Profiles' folder. " But how can I find "Profiles folder" when I have exit Thunderbird??? Lasse

Hello Toa-Hall I have found that I am using 32 bits version of THunderbird but my system is a 64 bits operating system. Should I download the 64 bits version of Thunderbird?? / Lasse

How to find profiles:

By default, Thunderbird stores profiles here:

• C:\Users\<Windows user name>\AppData\Roaming\Thunderbird\Profiles

Additional info:

• https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data

In Thunderbird

• Help > Troubleshooting Information
• click on 'Open Folder'

A new window opens showing the contents of your current profile name folder.

Exit Thunderbird now

You are currently viewing a profile within the 'Profiles' folder. Go up the directory to see the contents of the 'Profiles' folder. Then you will be able to remove those unwanted profile name folders. Do not delete the profile you are currently using.

re: I am using 32 bits version of THunderbird but my system is a 64 bits operating system. Should I download the 64 bits version of Thunderbird?

As you are using a Windows 64bit system, this meant you could have used either 32 or 64 version of Thunderbird. I'm also using Windows 64bit system and 32bit Thunderbird and I've had no problems. I would stay with 32bit as everything is sorted.

If you had used TB Win64 bit then it would have been installed in the C:\Program Files folder. The win32bit version is installed in the C:\Program files (x86) folder. Both work perfectly ok.

Hello again, I have now removed the two profile folders (default release-1 and default release-2) from the profiles folder. However if I look in "profiles" (under Help>Troubleshooting Information>Profiles the two profiles I removed are still there also after I had restarted my PC. But everything looks ok.

You asked me to mark your first comment as "Chosen solution" but I have no such "button" I only hav (in Swedish) "Har detta svar löst ditt problem" which in English "Have this solution solved your problem" and the button "Problem solved"

Do you want me to mark the problem solved? best regard and thanks for all your help I will now made the same correction for Thunderbird in another PC /Lasse

Yes please.
