Thunderbird Community Forum

As explained in the subject line - title, I do NOT need nor use the Today Pane.

It use taking up needed space for the down arrow & popping up distracting me.

How do I eliminate it? I will even, if necessary edit Thunderbird to get rid of it.

'AND bold text' somehow, a new version of Thunderbird was created - downloaded and all my passwords AND bookmarks are gone. I looked for the profile, but it's new so does not contain passwords NOR bookmarks.

THANKS! Remain WELL & be SAFE!

I have been using Mozilla Thunderbird for many years without any issues.

A few minutes ago, I used Thunderbird as usual and then closed it. When I tried to open it again, it would not respond. I restarted my Windows 11 laptop, but after rebooting, Thunderbird opened as if it were a fresh installation. None of my email accounts, settings, or data are there.

I signed in to one of my email accounts, hoping Thunderbird would automatically recover my previous accounts and settings, but nothing happened.

I am using Windows 11 and Thunderbird version 140.13.0 (64-bit).

Could you please help me recover my existing Thunderbird profile, email accounts, and data? I would greatly appreciate your assistance.

Thank you.

Dell windows 11 computer self destructed and crashed hard. Lost Thunderbird emails but have an Acronis cloud backup. Have purchased a new Dell EBT 2250 computer with windows 11 pro.

QUESTION 1: What are the proper procedures of installing Thunderbird and recovering my past "stuff" which was located at C:\users\My-Username\AppData\Roaming where Thunderbird kept my email data..If I install Thunderbird on the box, it would create that structure to create the Thunderbird data folder.

QUESTION 2: What are the proper procedures in recovering Thunderbird past data before I open it to my email server (Yahoo) where I have directly been maintaining my new emails via browser. I was going to install Thunderbird, then replace the Thunderbird folder under the user/username/AppData/Roaming, but when installing TB forces you to give an email account and P/W to log into your email. I do NOT want to have the email at Yahoo brought down before I can confirm I have restored all my past emails from my backup Thunderbird fold.

Question 3: Is there a way of installing TB in order to get the structure it uses, then overlay the TB structure under my user id?

I didn't want to restore my new Desktop with the OS recovery method because of the completely different hardware that OS would encounter once it tried to come up under a completely different hardware environment.

Thanks to anyone who can help me in what I should do, Floyd Smith

I cannot get thunderbird to run on my computer (it runs fine on my wife's computer). I keep getting the profile can't be loaded error. I have tried the fixes recommend here but none worked.

Thunderbird is suddenly opening without any of my emails or folders, and asking me to set up an email account - so I put in my email details (I'm with aol) - and it connects to the aol server and my folders re-appear (initially without emails in them, but when I click on the folders the emails start downloading afresh from aol). So it seems that all will be well when the emails are all downloaded again. HOWEVER, after closing Thunderbird and opening it again, all my emails are gone again, and Thunderbird is yet again asking me to set up an account. I can do this again, and the same thing will happen again. Everything is lost again when Thunderbird is closed, and when I start it again, I will be asked to set up an account, and all my emails are gone yet again. I have been using Thunderbird for years and years and years. Suddenly out of the blue this happens, and I'm stuck with using aol's web mail platform directly (not great!!!) Also, Thunderbird suddenly looks different - like it's been updated (which I assumed initially had happened) but the update history still only shows the final release for Windows 7, so this is a bit puzzling, and an odd coincidence that the layout and appearance of Thunderbird has changed at the very same time it stops working for me.

I have a previous Thunderbird account, which resides on another computer. On my current Desktop, I downloaded Thunderbird, went to open and it says "Your Thunderbird profile cannot be loaded. It may be missing or inaccessible." I went this route because my original Thunderbird has many customized Files to which I put emails into. I can't figure out how to recreate that profile as your instructions are quite impossible to follow. Remember, most of your users are like me, a bit under the standard as far as programming skills. So, how do I get either: my original profile to be imported to my new computer, or, better, just open my new Thunderbird so I can use a different, newer set of email addresses? This is my preference. Please advise.

I have a profile set that uses IMAP and need to change this to POP. I have tried changing the settings and tried creating a new profile by exporting folders and files but nothing is working correctly.

One problem I have is that in the IMAP profile I now have a second email address that is the same address name but is a POP setup. This is confusing. When I use the POP email to export and then import into a new profile I again get two email addresses in the folder panel of the new profile and one of them does have folders but they are empty.

Below is a screen shot of the original IMAP Profile. The upper address has folders but they are now blank because I pasted them in the lower address. I have tried selecting/highlighting the lower address for exporting but when I do I get the two addresses but the folders are empty/blank.

Thank you for any help!

Copilot has prepared a message for me: Subject: Thunderbird always loads corrupted profile and ignores new profiles

Message:

Thunderbird is stuck loading the same corrupted profile and always shows the welcome screen, even when I create new profiles.

I used the Profile Manager via thunderbird.exe -p and created new profiles (“Clean” and “Clean2”). Both profile folders exist in %APPDATA%\Thunderbird\Profiles. However, Thunderbird still launches the same original profile every time.

Even when I select “Clean2” in the Profile Manager (with “Use the selected profile without asking” unchecked), Thunderbird ignores the selection and loads the old profile. Safe Mode (thunderbird.exe -safe-mode) also does not disable the welcome module.

This appears to be a profiles.ini corruption or a profile lock issue, because Thunderbird is not switching profiles even though the Profile Manager shows the correct selection.

Could you advise how to repair or reset the profile configuration so Thunderbird will actually load a new profile?

Thank you.

Good morning,

I’m reaching out because I’m having trouble with my Thunderbird email and need some assistance.

I was using Thunderbird without any issues before, but now all my old emails have disappeared. I can still receive new messages, but I’m unable to send emails like I used to. I also can’t recover or view any of my previous emails.

It seems like something may have reset or become corrupted, and I’m not sure how to restore my old messages or fix the sending issue.

Could you please help me get Thunderbird working properly again and recover my old emails if possible?

Thank you for your support.

I am using Thunderbird 140.15.0esr and have noticed that my Ashampoo Backup is not able to store my Thunderbirs files any more. I have looked up how to find the Thunderbird files and the posts mainly say :

C:\Users\<YourUsername>\AppData\Roaming\Thunderbird\Profiles\

But when I follow this path there is no Thunderbird folder in Roaming as shown in the attached screen shot

Can you help please.

My computer recently updated to Thunderbird 155.0. The Local Folders did not move along with all my contacts. I have backed up mu Local Folders and contacts into a file into a file. Using the forum I have cut and pasted all of these into the Local Folder in the new Thunderbird but they are not there in the new Thunderbird. Please explain how to restore them in the new Thunderbird. I would suppose i will have the same issue with Address Books and would appreciate help there as well. Many thanks for your help!

I have an email account that I have had for several years and I run it under Thunderbird. I have recently opened a Gmail account and understand that I can operate this under the same Thunderbird (I haven't tried it yet so expect a few glitches on the way, as per usual! There are plenty of articles covering this, so I live in hope)! Potential problem is: I have backed up my old profile account regularly and know how to do it (though I've not yet had to restore it and of course hope I never will), What worries me is that if I follow the procedure to add Gmail to my Thunderbird (and it works), will I get a single profile covering both email accounts which I will be able to back up in the way I am used to; or will I get 2 profiles including a new one for Gmail so I will need to back up both? A simple question but I haven't seen the answer anywhere yet!

Have been using Thunderbird for years. Tried to set it up so my wife could also use it but the profile was the same as mine so when I deleted her profile, it also deleted mine and now I do not have access. How can I recover my profile so I can have access to all my previous emails and email addresses??? Also, since I cannot access the profile it will not open the app menu so I do not have access to the version.

I have posted another question about my corrupted TB profile and restoring it. Having done the restore and looked through the profile folder it is clear that this is full of old files that are no longer supported/needed.

Is there a utility that removes these old files?

I'm not sure if TB updates should remove them but it doesn't appear to have done so.

When I read https://kb.mozillazine.org/Files_and_folders_in_the_profile_-_Thunderbird it is clear that there are so many of these that doing it manually would be prone to error. That resource also says it does not know what some of the files actually do.

Is there a better resource that lists just the latest files maintained by Mozilla?

If I do a new export does it only export the files it needs? The last time I ran an export the resulting zip did not contain all the files from the TB installation but I have no idea why.

Hello,

I need help recovering my old emails from Thunderbird.

I am using a POP account. Recently, I changed the message storage location from the C: drive to the F: drive. After doing this, Thunderbird only shows recent emails, while my old emails are missing.

Here is what I have checked:

The mailbox files still exist on the F: drive. Inbox file: approximately 1.1 GB Sent file: approximately 1.18 GB I also have a complete Thunderbird profile backup of approximately 2.73 GB. The profile contains prefs.js, the Mail folder, and all profile files. Some account folders such as: pop.accessarchitects.in pop.accessarchitects-1.in pop.accessarchitects-2.in have Inbox files that are 0 KB. However, another mailbox file named Inbox is about 1.1 GB, which appears to contain my old messages. Thunderbird downloads and displays new emails correctly, but it does not display the old emails. I previously had around 60,000+ emails organised into many custom folders such as Contracts, Bills, Axis Bank Statements, Notifications, etc. Some mailbox files still have large sizes, but Thunderbird does not display their contents. My folder structure F:\Mails\

   Inbox (1.1 GB)
   Sent (1.18 GB)
   Inbox.sbd
   Local Folders.sbd

Inside Local Folders.sbd, I also have mailbox files such as:

Inbox (~642 MB) contract & bill (~778 MB)

The data appears to exist, but Thunderbird is not recognising or indexing it.

My Questions How can I reconnect these existing mailbox files without losing any data? Is there a way to rebuild the indexes so Thunderbird recognises the old messages? Could the issue be caused by an incorrect profile mapping after changing the storage location?

I have not deleted the original mailbox files, and I have a complete profile backup available.

Any help would be greatly appreciated.

Thank you.

Hello, I urgently need help recovering emails and archive folders that have disappeared from Thunderbird.

Here is what happened: I had an email account configured in Thunderbird using POP3. Over the years, all the emails and the entire email history were downloaded and stored locally in Thunderbird. I also had several archive folders containing important emails and documents.

The mailbox was recently moved from the old mail server to a new mail server using IMAP. The account was then set up again in Thunderbird as a new IMAP account.

The old POP3 account/configuration was left untouched, because I expected the old emails and folders stored locally in Thunderbird to remain available.

However, after setting up the new IMAP account, I can no longer see the previous email history or the archive folders from the old POP3 account. Some of these folders contain very important documents that I need to recover.

I would like to emphasize that I am not asking to recover emails from the old mail server. The emails and archives had previously been downloaded and stored locally in Thunderbird through the POP3 configuration.

Could you please help me determine, how I can locate and restore the old Thunderbird profile or Local Folders? The emails and archive folders are very important, so I would really appreciate detailed instructions on how to safely recover them. I have not intentionally deleted the old emails or archive folders.

Technical information: Email address: biuro@wojciechprzybylski.pl Old mail server: server.go4win.pl Old account type: POP3 Approximate date of the migration: 15.09,2026 Missing folders/emails: Archiwum

Thank you very much for your help.
