Hi, Just got computer back from shop where - rather than upgrade - they did a clean install of Win11. I was under the impression from them they'd backup everything on a new "backup" drive they installed to double my capacity as part of the upgrade process.

They're version of backing up Thunderbird left me with a folder "Thunderbird_profile_backup.zip" that is 9,698,657kb in size.

I am attempting to install Thunderbird on the essentially new computer and restore all data from the previous installation.

Is this even possible anymore at this point?

I have data in that file that is important not only financially but archived family info from now deceased members... I'd really like to recover it.

In short help! lol.

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 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

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.

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 followed these directions - https://support.mozilla.org/en-US/kb/export-firefox-bookmarks-to-backup-or-transfer but Firebox only exports this data in the bookmarks.html file and attached image! Bookmarks Menu

How can export all of my bookmarks in Firefox?

My thanks again to sfhowes, Rick and others for assisting me to get back my ability to once again send e-mails from Thunderbird. Now for the next step.

Just days ago, I migrated my years of Thunderbird e-mails on a POP protocol to IMAP. Before doing so and before also uninstalling my old Thunderbird because of e-mail sending problems and then reinstalling a new version, I saved a profile. Now with the most current version of Thunderbird, I lost (i)a decades worth of saved inbox e-mails (but for the last 2 years), (ii)I lost all of my sent e-mails but a few odd ones, (iii)I lost my archived e-mails in Local Folders and (iv) I lost all of my contacts and saved group e-mail address lists.

My profile is saved on an external hard drive. Obviously the new installed version of Thunderbird must have somehow found the last 2 years of my inbox e-mails but nothing beyond that as mentioned above. Can you share please a recommended procedure where I can better import what I assume I saved correct on the profile I saved twice (I saved a master folder named Profile and separately saved 4 folders - 2 folders ending in default and 2 ending in default-release. Thank you.

I am trying to upgrade from 128 esr version to the new 139 version. I tried several ways to transfer data from the old version to the new version - I tried to export and import a the Thunderbird zip file. I also tried to open profile manager and creating a new profile that refers to a copy from my old version. Nothing has worked. In the old Thunderbird 128 version, if I select Help and Troubleshooting Information and then Open Folder next to the Profile Folder I get an error in Thunderbird that it can’t find my profile. I get the same error message when I go to Tools, export and select "open profile folder." This in spite of the fact that the old version continues to correctly display my contacts, tasks and events

After several hours of this, I finally decided to download version 139 using the standard Mozilla set up even though my Thunderbird 128 version is located someplace else. So, at this time I have two working versions of thunderbird on my computer – the old 128 version with all my data and the new 139 version with no data.

I think I need help figuring out which Profile has my contact, calendar and task data. Then I need help getting it to the new version.

Thanks

I have a new laptop and did a backup of my files on the older laptop (Windows Home) and restored them to the new laptop (Windows Pro). Then I installed Thunderbird on the new laptop and I already had e-mails on it. But there are thousands of e-mails in the wrong folders.

The Windows Home has Thunderbird 128.10.oesr (32 bit) and the Windows Pro laptop has Thunderbird 128.9.2esr (64 bit). What should I do? Should I uninstall Thunderbird on the new laptop? Then what?

I need to do something with a profile folder, right? But what?

Please help.

It's a mess right now.

Dear Team,

When my Client device installs From Firefox 102.7.0 ESR to Firefox 128.7.0 from SCCM. (The case is First install the Version 102.7.0 then save the Bookmarks and then uninstall. Second Install the 128.7.0 then check the bookmarks)

user profile Bookmarks are not mapped in Firefox. When I check C:\Users\Tests\AppData\Roaming\Mozilla\Firefox\Profiles I can see the xxxx.defaultesr

I don't understand why the bookmarks are not linked in Firefox. Can you please help? I would be thankful to you if you could share me the .bat script

Thank you

I cannot find anywhere on my Firefox browser where I can export my personal bookmarks to another browser (Duck, Duck go). I do not like the most recent Firefox update, changing my everything Firefox!

Moving from Chrome to Firefox on Android Tablet V13 and phone V14. Note: NO desktop/laptop computer is owned. Firefox account is setup. My Chrome bookmarks are synced on both Android devices. Want to transfer Chrome bookmarks to Firefox on both Android devices. Then have the ability to continuously Sync Firefox bookmarks between the Android devices. Am new to Firefox and knowledge of navigation etc within the browser is very lite. Please provide step by step instructions to help me with this inquiry.

15.18.0 how to export to mobile from settings in the desktop thunderbird so i can use my android phone--if it will help, on my desktop there is no Export to mobile in settings!!!!!!!

Hi, I use TB 115.18.0 (32-bit) on win 7 machine. In order to transfer it to another computer I tried to copy the profile to a new disk and it failed. An error message stated that "The destination you have specified does not exist". I manually copied the profile folder, and found that the problem occurs when attempting to copy the file (no file type is given. File name is printed bolt) as follows: mozilla profiles>cc739xtg.default>mail>local folders>unsent messages. (1,835,282 KB file) Unsent messages.MSF (6KB file) was copied with no problem. I did not find a way to open unsent messages file to read its content. Unsent messages does not show in my TB folders. As far as I understand there are no unsent messages in my TB accounts. 1. How to overcome the unsent messages file copy problem? 2. Can I try to delete both unsent messages and unsent messages.msf files without damage the profile? 3. How can I open unsent messages file to read its content? Thank you for your assistance. David
