Hi, I'm having issues moving a 10 year old Thunderbird installation on a Windows 10 Pro computer to a new Windows 11 Pro PC.

I looked at all the guides & prior support messages and followed the instructions carefully. My old Windows 10 installation was in a custom directory (G:/Program Data/Thunderbird). I ensured it was updated to the most current version and closed it before moving files. I installed Thunderbird on the Windows 11 machine, went to Troubleshooting Info and found the folder that it used for the profile (when I go to profile editor, there are 2 profiles listed in the new build - I verified that I was in the directory for the default profile). I then closed Thunderbird on the new PC.

The two computers are on the same network so I moved all the files from the old location to the new location via just drag and drop. Of note, I couldn't "go up 3 levels" on the original machine's directory as per the instructions because, well, there weren't 3 higher levels of directories - I just moved the Thunderbird to Thunderbird on the new PC.

When I open Thunderbird on the new PC, it still acts like it's a new installation, except I do have my Address book. I tried deleting the second profile it had created; no different. I tried creating a new profile and specifying a directory somewhere else (eg. C:\Program Data\Thunderbird) and moving the files there - no different. I tried copying (presumably inactive) Thunderbird folders from the old computer C:\Users\~\Roaming and \Local over to a similar location on the new PC - nothing changed.

Anybody have any other ideas of what I'm doing wrong? Thank you!

I have downloaded Thunderbird Android and want to write an email but my address book doesn't seem to work when I start writing into the address ("to") field. How do I connect my address book to Thunderbird?

I have the Android T-bird app on my Google Pixel 9.

I am having constant problems with it not syncing.

This morning, when I swiped down, the kept spinning but did not connect. When i tapped the sync icon at the bottom left of the screen, nothing!

Nothing changed after rebooting the phone, which BTW takes almost twice as long as the reboot on my previous Samsung phones.

I have now uninstalled and reinstalled, and imported my settings using the QR code on my desktop. It imported my accounts, but asked me to sign in or sign in later. There is no link for signing in immediately, and sign in later does not allow any sign in opportunity.

I now have no emails imported to the app.

Any help would be appreciated

I was forced to erase my PC because it was infected with malware. I saved my Tbird profile to my HDD before erasing. I pasted the saved profile to %Appdata% >Thunderbird, copying 1,777 items. When I brought up Tbird, I got the Account Setup window, so I don't think the profile was actually there. What did I do wrong?

I have 3 computers and I want to make sure Thunderbird is synchronized on all 3. Yes, I have checked your forums for help. Here’s my configuration:

Main PC – used daily. Thunderbird has 4 email accounts. One is IMAP, the others are POP. Backup PC – Used only occasionally. files on this computer are synchronized with the Main PC about once per month. The email accounts are the same as the main computer. Laptop – Used only occasionally. files on this computer are synchronized with the Main PC about once per month. The email accounts are the same as the main computer.

I have read articles on how to move profiles, but I have not come across one that does what I want to do. Also, I am confused about whether filters can be duplicated on more than one computer. I have seen suggestions to just use IMAP (which might work for some, but not all, accounts), but that doesn’t address how to copy filters and keep them synchronized.

Here’s what I would like to do.

Step 1: Back up Main PC Step 2: Copy Thunderbird emails and filters from that backup to the Backup PC Step 3: Copy Thunderbird emails and filters from that backup to the Laptop.

When all steps are completed, I would expect that if I open Thunderbird on either the Backup PC or the Laptop that all messages, folders, and filers would be exactly like those on the Main PC.

Is this possible? If so, what must I do to ensure everything works as I would like?

Thanks, Alan

Hi Firefox I installed Firefox and I have a problem with transferring passwords from Chrome to Firefox because I don't see the option to export hala to it, how can I do it and do I need the PC version to do it? Best regards, Kacper.

I have the Android version of Firefox

I am new to Firefox and tried to import the Google Chrome Bookmark Toolbar bookmarks. This did not happen and need to get the items listed in the Chrome Bookmark Toolbar into my Firefox Browser.

I have an 8 year old PC that I have been using Thunderbird on its entire life. I have 5 email accounts (from my own website if that matters) on it for personal use that have tons of information.

I bought a new computer and have not been able to move my old data to it. The old computer uses Windows 10 with Thunderbird Version 115.5.2 (32 bit). The new computer uses Windows 11 and I have tried several Thunderbird versions with the current one being 128.12 0esr (32 bit). I have added one of my email accounts to my new computer, but it contains none of my previous data (emails, contacts, directories, etc.), just a bare bones account that only receives new email.

I have repeatedly tried to move my entire source computer setup and data going through all of the described steps including copying the previous Thunderbird folder to a flash drive. I then follow the directions for copying and pasting my source data into the new computer's "roaming" section. It goes through all the steps including asking if I want to overwrite existing files. I have almost 14,000 files and as the process continues, I can see file names being added just as I would expect.

After everything is complete, when I restart Thunderbird, the only access I have is once again to the bare bones new email account. There is no data, nothing at all, from my source computer.

Help please, this has gotten beyond frustrating.

this is supposed to have a QR code, but it does not load. I have attached a still screenshot below.

I also cannot upload images using Firefox to Messenger. The large purple image is a result of an upload, but it should be a picture of a woman saved from Krita.

I tried a setting called "Refresh Firefox" and that fixed it but only for less than a day. whats going on?

Switch computers from windows 10 to windows 11. I downloaded bookmarks history from windows 10 on an external drive in html.

On new windows 11 computer, I'm trying to configure book marks. Turned off chatbot. Firefox or windows 11 is populating my sidebar with internet history I no longer use? How do I stop this and how do I import my bookmarks? i tried the import , similar to export, but it is not showing up?

Appreciate any help. Brian

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

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?

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 want to migrate everything from windows to linux, i've already synchronised browsers on both systems, but settings on linux didn't get overrided.

How can i make browser on linux exactly the same as on windows (including settingd)?

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?

Hi,

I'm trying to move Thunderbird from my Windows 10 laptop to one where I just installed Linux (Zorin Pro 17.3). I followed the instructions here: https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer

I installed Thunderbird 140.4.0 esr, which is the latest version. Both laptops now have that version installed.

But when I open TB on the Linux computer, and close the Account Setup window, and go to the Troubleshooting screen, next to "Profile Directory" it says "Open Directory", but when I click on that, nothing happens. So how can I paste my TB profile? Do I have to start a new profile first, and then copy over that?

I installed TB from the "Software" area, which I believe is a Flatpak. I'm very new to Linux, so just fumbling around here. There were 3 options of Thunderbird. I installed the one that had the most information and seemed most up to date. That was confusing.

I would LOVE some help on this.

Thanks!
