Thunderbird Community Forum

Hello,

Moving from an older Ubuntu 18.04 machine where Thunderbird is limited to version 102 to a newer machine running Mint 22 where the current version is 128.6

According to https://support.mozilla.org/en-US/kb/upgrading-older-version-thunderbird This should work without issue but the latest version mentioned in the article was 115.

Any change since the article was written? Do I need to install older versions to handle the migration to the latest?

Alternately would using the Export / import tools be better for this task than transferring the profiles?

Thank you

I've been using Thunderbird for years under windows 7 and keep my data on a separate drive. Is it possible to migrate or move the whole program and data base into Linux at a later date? I haven't used Linux yet, but need to know if it's possible to successfully make the move before I jump. Thank you.

I didn't find anything quite like this in the forums.

Trying to export my Thunderbird ver 128.9 to my mobile; I foolow the instructions and get to the page that says "Scan the QR code". But there is no QR code to scan! If I select the "Export" button, I get a request for a PIN code. I know nothing about a PIN code so I follow the "Forgot my PIN code" which tells me I should go to "Settings/Accounts/Sign in Options" There is no "Accounts" selection under the Settings menu.

As with millions of people I am forced to abandon my Win 10 computer for a Win 11 one. Since I have been using TB for many years (and before that Eudora) I would like to transfer all of my TB “data” to the new computer. I have copied my profiles to the new computer. The first thing I tried was to replace the new TB profiles with the old ones. Some apparently transferred and some didn’t, like all of the email folders. Could you please give this old man simple instructions on how to transfer TB?

I spent a lot of time setting up a bunch of message filters and organizing messages into folders. I had created about twenty filters, and was running them and moving messages, etc.

My computer crashed due to a flaky display card (intermittent, but happens infrequently, so not corrected yet.) The only recovery possible is turn the power off and restart the PC. When I restarted Thunderbird, all my filters were gone. I have pretty good "save your work often" discipline, so I thought I was covered once the filters appear in the "Message filters" dialog. I don't see any option to explicitly "Save Filters", but it is possible I am missing it somehow.

How and when does Thunderbird save these? Is there something I need to explicitly do? Close and reopen the filter window? Exit Thunderbird?

Running Thunderbird SUPERNOVA 115.10.1 (32-bit) on Windows 7 Professional. I'm seeing an update to 116.0 is offered now.

Thanks for any advice.

I tried transferring TB to new computer, nothing has worked. w11 TB148. Manually didn't work, tried coping from Troubleshooting Information/profiles. I don't know why there are 2 TB's? Under local and roaming but I tried. The video is out of date. It's a new install of TB so it opens with create account, both computers W11 and TG148! Please somebody tell me what I'm doing wrong? Thanks.

Have TB on my laptop (146.0.1 (64-bit) on Win11) all set up the way I want it. Would like to "clone" those settings/profiles to my desktop. AI site said, "Copy profiles folder and profiles.ini to the new machine." Didn't work. Asking me to set up from scratch. Laptop is on "standard" edition, think desktop is on beta. Is that the problem? What do I need to do?

I downloaded Thunderbird to my new machine, followed instructions to copy the Profile Folder from the old machine and pasted to the new machine. I didn't get a message asking whether I wanted to replace the data on the new machine. When I started Thunderbird, I am not seeing all the data I expected - no address book, only 200+ emails, no sent emails. What did I do wrong?

Hi all, I have a new Computer and I'd like to transfer my Thunderbird installation with the complete settings (folders, mails, archives, address-book, ...). Also the calender would be of interest, because I have some settings which I want to keep. Is there any way to do this? I have access to my old computer, so I could export everything there and import that on the new one, but I did not find something to do that. Can you help me? Regards, Gerhard

My Thunderbird Desktop Version 140.9.0esr 64 bit. Help please. Installed Mobile T'bird on android mobile. On Desktop (MS Win11) T'Bird followed Settings - Export to Mobile - included all email accounts and Passwords - Export resulting in pop up box requesting Pin number. Don’t know a Pin nor can find a Pin nor find Settings - Accounts - Sign in options to change it.

My hard drive is going to have to be replaced, how do I move everything to a new hard drive. I pay my bills from folders I have added in 'Tbird so it is imperative that I move it all intact AND that I have access to all of it after I do manage to relocate it to a fresh hard drive. Thanks, God bless....Arthur Kelly

I transferred content via a Time machine backup of my old macBookPro (Ventura 13.6) to my new macBookPro (Sequoia 15.6.1). The Thunderbird folder is identical on both computers and contains two profiles: a newer 9389qbc0.defalut-release and an older r13n4n5e.default. The former presumably is active on my old computer and is the one I want to view/use on the new computer. However, the older version appears on my new computer. How do I get Thunderbird on the new computer to recognize and load the newer profile? Thanks much for any assistance!

I just deleted the folder C:\Users\alan\AppData\Roaming\Thunderbird and replaced it with a backup I made a few days ago. To my surprise, when I opened Thunderbird, I could see messages that I'd downloaded today. What is going on?

Hi all.

Previously, when moving to a new computer (Windows 11) with Thunderbird, I would install a new instance of Thunderbird on the new computer and run it once. This created the default Thunderbird profile in the Profiles directory. I would then copy the contents of the existing Thunderbird profile into the new one. This allowed Thunderbird to be fully operational with all accounts and filters working, requiring no further setup.

In version 140, I have followed the same process. While I do see all of the email accounts, they are not functioning.

Any advice on how to do a migration with Thunderbird 140 version?

Hi, i copied my Thunderbird (windows 10 Prof)) to a new Notebook (windows 11 Prof) by overrighting the Standard-Profilfolders (in ROAMING and LOCAL) of the new Installation with the Folders of the old Installation (both are Version 146.0.1 but old is 32-Bit and new is 64-Bit) I use more than 2 accounts, and in some accounts, I created subfolders in the 'In' folder to preselect the emails by rules after they arrive Result is: alls Subfolders are missing and some accounts' 'In' Folder are empty. The Account settings seems to be corrct, means i can load new EMails even if the IN-Folder is empty. But i miss the exosting EMails there and the Subfolders content.

The summary says it all. My T-bird acc't combines both outlook and gmail and now I wish to transfer the data into a new T-Bird (account?) on a new computer. I'm going from an ASUS Zenbook to a HP Omnibook AI.

Many thanks ! I should sign my name as "Totally Lost". Regards, Andre

I am running Thunderbird 140.8.1esr on macOS Tahoe 26.3

I created an IMAP account in Thunderbird to replace a POP account

I want to copy the Thunderbird message filters from the POP account to the IMAP account

I read articles on Mozilla Support and these said to copy the msgFilterRules.dat file but I cannot find this file

How can I copy the message filters?
