I want to install Thunderbird on my new computer (Windows 11) from my old (Windows 10). But I cannot open the downloaded version of Thunderbird - it keeps saying there is no profile. Of course there is no profile before I have installed it! I de-installed and re-installed the Thunderbird program, but it keeps saying the same thing. How can I open Thunderbird to install the profile?

My C: drive is almost out of available memory and the following profile, jrqu4wd0.default-release, is the culprit. If I delete it what affect will it have on Thunderbird.

Systemordner Thunderbird umbenannt und neues Profil erstellt, alle E-Mail Konten neu integriert, Teste i.O.,

Aus alten Thunderbird Ordner war plötzlich keine Profilordner mehr vorhanden? Wieso plötzlich das? Sicherungen hatten leider auch keinen Profilordner von Thunderbird gesichert. Warum werden diese nicht gesichert?

Thunderbird switched automatic to Freedom. No possibility to avoid. All connections where lost. After input connection data mail where downloaded. But over 2000 old local stored mail are gone.

How to restore all old local mails, structure and archives?

Hello, i am currently woking on an issue inside of the latest version of thunderbird. We have the data file for thunderbird located on the desktop. It shows as 37gb of data. however when we try to open the data file from inside of thunderbird. We cannot see any of the information from the folder. If i go all the was into the data file directory and select sub folders, they will open inside of thunderbird and show correct data. however, when i set thunderbird to open the entire directory with its sub folders, the application does not display any of the sub folders or information from inside the folders. We have attempted to go into properties and repair the file from inside thunderbird. It shows as 0kb file inside of thunderbird. it shows as a 37gb folder on the desktop. Once again to clarify, i can access specific directories inside the data folder but not the data folder as a whole. Any support or suggestions would be greatly appreciated. Thanks You

I assume there was an automatic update overnight. When I started Thunderbird this morning I was asked to enter our account information - which I did. However I had no Local files. I have a copy of the Thunderbird directory from two months ago - I copied this in to the Thunderbird directory in Local Apps/data but i still have no local files data. I have several years of saved emails that I want to keep available. Any Suggestions how I can resolve the problem.

Three weeks ago I attempted to migrate my TB profiles from a 2014 mini-mac to a 2024 mini-mac. I thought I did a better job of backing up my profile using CCC than I actually did. In the migration to the new Mac I lost all my subfolders from the last 20 years. Apple created a new Profile and 2 restoration Profiles on the new Sequoia based mini-mac. I wasn't familiar with these and panicked. I copied those files, took them back to the original mac and tried to follow Toad-Hall's method of restoring the subfolders recommended to bmack1 on 23/11/22. However, I failed to carry out the step of going up two levels in the path of the Library to copy the entire "Thunderbird" file and only copied the Largest restoration file. This in turn, "contaminated" the 2014 original Thunderbird mail profile and only an Inbox and Trash subfolder remained. Today, after 3 weeks of searching and reading the generous contributions of this community, I came across a post explaining that the "sbd files" will show the subfolder headings I created in the original sought after Profile. And I found it!!! My problem is I have re-read Toad-Hall's method of re-installing the original Profile and tried to carry that out to the letter by placing the old Profile within a Thunderbird folder and switching it with the current one. But it's still listed as the "Restoration qqg...file" and probably shouldn't be, but I don't want to go any further and risk losing it because I feel I almost have it. So any guidance would be greatly appreciated. Thank You.

I backed up Thunderbird and reloaded it after I had been hacked in gmail, but now I have 2 profiles accessing the same gmail. One shows the gmail address and the other is my old "local" profile. The old one has my typical 16000 emails, while the new one shows 30,000 emails with no doubles. Can I delete the new one?

Hello, I am using Time Machine to backup my Mac, but the tool excludes Thunderbird. In settings I have not excluded any files. My Thunderbird folder is fairly large, 25GB - thanks to the great archiving features of Thunderbird, How can I include Thunderbird folder to backups? Thanks in advance for helping. BR Tapio Heikkila

Hi,

I have transferred Thunderbird to a new computer. It opens fine, but it's looking for me to enter new info all over again.

So it looks like it is not finding the right info in the profile.ini file.

Please tell me how to fix this, and let me know in which folders the email information is stored, in case I need to back up all my emails.

In my Thunderbird email client I have 4 email addresses.

The program is in: C:\Program Files\Mozilla Thunderbird\thunderbird.exe

The Profile Folder in Thunderbird itself lists: zvhtqvg2.default-release-1

But in AppData\Roaming\Thunderbird\Profis lists 2 files: 0jyd0ev.default-release zvhtqvg2.default-release-1

In Windows(C)\Users\ted\AppData\Roaming\Thunderbird the profiles.ini file list the following:

[Install746F856C10C5FA7C] Default=Profiles/0jyd0ev.default-release Locked=1

[InstallD78BF5DD33499EC2] Default=Profiles/zvhtqvg2.default-release-1 Locked=1

[Profile1] Name=default IsRelative=1 Path=Profiles/0jyd0ev.default-release Default=1

[Profile0] Name=default-release IsRelative=1 Path=Profiles/0jyd0ev.default-release

[General] StartWithLastProfile=1 Version=2

[Profile2] Name=default-release-1 IsRelative=1 Path=Profiles/zvhtqvg2.default-release-1

Thank you, Ted

I've read the articles on moving Thunderbird to a new computer. My old computer died but I have a full backup and have replaced the Thunderbird directory a number of times according to the instructions to move TB to a new computer. I have even uninstalled and reinstalled TB to match the version on the old computer (140.4.0.0). It comes up and shows over 8,000 emails, but ALL are in the inbox and none of the probably hundreds of folders and sub-folders show up. I have found some of the names in the Profiles directory but they don't appear in the TB window.

I FINALLY was able to find the original profile, all messages in the In Box, plus all folders with their contents. 'Lost' when our ISP's ' tech support person ' had me close/remove the TB POP3 account and create an IMAP account).

I need to merge the new small profile (In Box & with basic folders) into - onto the BIG, original, profile. So each time I get/check mail everything goes to, ends up in, the Thunderbird account containing all the OLD data and new working account.

Please remember I am barely TB literate, so start at 1 (A), not 27 (Z)& no tech words. Nor acronyms please.

Thanks! Remain in GOOD health, be WELL, 'n be

Got up this morning and stared up Thunderbird as I always do but got a 'new account dialog'. All of my emails, folders, settings, etc. are gone. Went through the Help - Trouble shooting process to find the old profile. There are three profiles listed in 'About Profiles' and if I launch with any of them, all I get is a new setup. Freaking out here as I have 10 of thousands of emails, in multiple email accounts, in a relatively complex folder structure which includes online and local folder storage. I have a feeling that Thunderbird updated last night and is the cause of this problem.

Running Windows 10 Pro v 22H2, build 19045.6332 . Thunderbird 140.3.1esr (64-bit)

Hello Thunderbird Team I am facing a crisis and am praying you can help me. I have been using Thunderbird since 2021. I had setup my account and archives by year containing messages in Folders (Inbox, Sent & Deleted). During a recent laptop migration, I accidentally deleted my profile on my old laptop. I immdeiately recreated it. However now all email stored in my inbox has disappeared. Second, I cannot seem to locate the archives. So I have 2 requests for urgent support: 1. How do I locate the messages in my inbox prior to deleting my profile? 2. How can I recreate the archive with folders? I can see that the profile folder is a massive 22 GB. So the data is there somewhere. Please help me recreate my email profile so I doi not face a business crisis. Thank You Warm regards Milind

My old Windows10 computer died, but I have an external backup with my Thunderbird profile folder. In the meantime, I have been able to resurrect an old Windows10 computer to continue receiving email, but was not successful transferring the backup profile. Thus, I have "new" profile on this second computer containing only the recent emails not in the backup profile.

I've purchased a new Windows11 computer. My question is: How can I merge my old emails in the backup profile with the recent emails received after the backup was made? In other words, is it possible to merge two separate profiles into one? Thanks.
