I do not know what the cause or solution is, but it sounds like what is reported at https://bugzilla.mozilla.org/show_bug.cgi?id=1795272

That may be - not for me to judge. But now I see that my address book is becoming empty - everything is disappearing! How does one deal with this? Delete everything internally? Then what? The db is still corrupted, presumably. So what files must be deleted? As it stands I have lost everything anyway.

But the key question is how did this come about, how can it be avoided?

Thanks.

This is getting silly. I have just closed in an orderly fashion and restarted TB:

Is there an error file than be deleted? Why can the profile not be found?

The error messages are useful, but what do you see occuring? We need more information.

In the Address book Q: Do you see all the names of the various address books? Q: Are some address books missing?

Q: Are all the address books visible, but they do not have contents - contacts are missing?

re: Why can the profile not be found? Q: Has Thunderbird started and it is acting like you have a completely new profile ? Q: Is it asking you to create a mail account? Q: Is the 'Address Book' only showing the two default address books and both are empty?

If you have any Anti-Virus or cleanup file type program like CCleaner or WiseCleaner please make sure none of these products can scan/have access to any thunderbird profile folder or file.

Let's check whether this problem may have occurred because a new prefs.js file has been auto created and it's missing data, so cannot locate files.

Q: What OS are you using eg: Windows, Mac, Linux ?

If Windows OS: Access profile name folder

• Menu icon > Help > More TRoubleshooting Information
• Under 'Application Basics' - half way - Profile folder - click on 'Open Folder'

A new window opens showing you the contents of your profile name folder. Make sure you have the 'view details' option selected. Make sure you have these column headers - Name, modified date, Type, Size, date created

The Thunderbird default address books are called : 'abook.sqlite', 'history.sqlite' Other address books tend to be numbered and called eg: 'abook-1.sqlite' and you may have one called 'impab.sqlite'. You may variations eg: abook-1.v2.sqlite

Please post images showing all those files.

Then scroll to locate the 'prefs.js' file Q: Do you see more than one 'prefs.js' file? Perhaps it has a number eg: 'prefs-1.js' Please post an image showing all the 'prefs.js' files you can see.

Open the 'prefs.js' file using a text editor eg: Notepad Scroll to where you see lines beginning with this: user_pref("ldap_2.servers. Please post an image showing all those lines.

In the Address book Q: Do you see all the names of the various address books?

    - Yes.

Q: Are some address books missing?

    - No (except I have now deleted the imported Eudora AB since that seemed to be badly behaved.  The problem has not gone away.

Q: Are all the address books visible, but they do not have contents - contacts are missing?

    - Some seemed to be.  Also blank ones present that cannot be deleted.  There are too many address to check manually, collected over many years

re: Why can the profile not be found? Q: Has Thunderbird started and it is acting like you have a completely new profile ?

    - No

Q: Is it asking you to create a mail account?

    - No

Q: Is the 'Address Book' only showing the two default address books and both are empty?

    - No

If you have any Anti-Virus or cleanup file type program like CCleaner or WiseCleaner please make sure none of these products can scan/have access to any thunderbird profile folder or file.

    - Not used.

Some of these look as though they might be deleted - which to keep (all are backed up anyway)? Why are some created dates younger than modified?

There is only one prefs.js: prefs.js 2023-05-08 15:57 57 KJB 2023-05-08 15:57

user_pref("ldap_2.servers.history.uid", "d54cd30a-5659-4348-abd7-1e785854d815"); user_pref("ldap_2.servers.pab.uid", "12d69522-242d-49f7-9418-682debd78ba0");

Thanks.

(sorry, careful line spacing wrecked when I posted!)

If you posted some images it would be better.

cannot see how, but ...

re :Why are some created dates younger than modified?

An image would help explain things better. - UPDATE Thanks for images but in future please make sure all the column headers are displaying as well.

'abook.sqlite' - this is the Personal Address Book 'abook.v2.sqlite' and 'abook.v3.sqlite' are backups of the 'abook.sqlite' file and they were created when Thunderbird performed certain updates. The last backup was on 2023-02-05 12:44, although some files got an immediate backup to V3-1 only one minute later.

'history.sqlite' is the 'Collected Addresses' address book. 'history.v2.sqlite' and 'history.v3.sqlite' are backups of the 'history.sqlite' file and they were created when Thunderbird performed certain updates.

impab.v2.sqlite 2021-10-26 17:47 1,696 KB 2023-02-05 12:44 impab.v3.sqlite 2022-08-25 10:46 1,696 KB 2023-02-05 12:44 impab.v3-1.sqlite 2023-01-24 15:01 1,696 KB 2023-02-05 12:45

You had a folder which you imported and it was called 'impab'. The three files you mention - see above - all of them are versions of backups. But the 'impab.sqlite' file in not mentioned But you did say "- No (except I have now deleted the imported Eudora AB since that seemed to be badly behaved."

It's easy enough to Exit Thunderbird, then copy the 'impab.v3-1.sqlite' and into same location and then rename it as 'impab.sqlite' which would get the file back, but it will not get detected if that file is not mentioned in the 'prefs.js' file.

But it may explain why you were getting an error :

• NS_ERROR_FAILURE: No directory for uri=jsaddrbook://impab.sqlite AddrBookManager.jsm:266

It must have known about the file you deleted, so I was expecting it could be in the pref.js file.

re :There is only one prefs.js: prefs.js 2023-05-08 15:57 57 KJB 2023-05-08 15:57

OK that seems fine.

re :Contents of prefs.js - user_pref("ldap_2......

I was expecting more than two lines - especially as you also had an address book called impab.sqlite. please post an image that shows everything that mentions 'user_pref("ldap_2.servers...'

images: OK. The dates were in (default) order modified, created. Hence the confusion.

But the 'impab.sqlite' file in not mentioned  : because of the deletion?

But it may explain why you were getting an error : that was before I deleted it.

I was expecting more than two lines : there were only two lines ... see attached.

Now I am seeing many errors of almost (but not quite) uniform kind (image attached).

The question is how do I clean this up?

Thanks.
