I've been upgrading from Win 7 and Thunderbird (TB) version 68.1.1 (32 bit) to most recent TB Version 145.0.7632.117 (Official Build) (64-bit) NOTE: From a old Dell Inspiron 580 to Alienware Aurora Act 1250.

With new system and TB, I can export with handy-dandy exporter for TB 145.0.7632.117 but need them off old Windows 7 box. I see that the Legacy Add-on "Password Exporter" doesn't have versions high enough to work with most recent TB. And, I can't find a exporter for the old TB.

I have tried listing them in the old TB, but can't Capy/Paste. I made good quality screen caps and pieced them together in to one list. I was hoping to put the screen cap through a OCR but too costly for just one operation, and won't put it to a Online OCR - not when the image contains such things as ID';s and passwords.

Is there any way the data and passwords can be extracted from the old TB?

Many thanks for your help,

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 The video is out of date.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.

I have a new PC and want to copy my existing filters on to my new PC. I have 116 filters set up and do not want to have to manually add them. I tried exporting my profile from my old PC but it is 38Gb

Hallo, ich habe meine E-Mail-Konten in Thunderbird umgestellt von POP zu IMAP. Meine Filter-Einstellungen waren bisher gültig für "Lokale Ordner" (die Filter musste ich manuell starten) Wie kann ich die Filter-Einstellungen auf den Posteingang meiner IMAP-Konten kopieren/migrieren? Danke, und Grüße aus Berlin

Hello. I have followed the instructions to copy the profile file to a drive and take it to the new computer so my Thunderbird will be the same on both laptops.

BUT I get a message that the profile file is not available. And I searched for the file by name and found nothing!

The actual message is attached.

I need to copy my emails to the new laptop.

I am updating from an old iMac to a new MacMini.

My new macMini does not seem to like my old Thunderbird program so I have downloaded a current version. 

How do I transfer all my old email contacts and old emails to the new platform? I am, in no way, technically savvy so I need simple answers, Many Thanks, John

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've been using Thunderbird for many years. My current version is 45.2.0. My computer runs Linux Kubuntu 15.10

So yes, it's ten years old and it's showing its age. I have a new box I built, and have Kubuntu 25.04 installed. It installed the then current version of TB. I have yet to set things up, but migrating is a priority now.

Some solutions say (on ubuntu/kubuntu) to just copy the directory "/home/username/.thunderbird/profile.default" from the old to the new box. I would likely do it by zip, rar or ssh transfer.

If I do that, when opening up TB on the new box, does the data get converted? and if so, is it automatic? It seems to me that after then years, the data format would have some changes.

I'd appreciate any insight on this. Thank you.

Hello, I'm getting a new PC next week and I am concerned how to install Thunderbird in the new PC. And is there anything I need to do in the old PC to make the move smooth so it continues to work.

Thank you for your time and efforts ahead of time.

I want to transfer my files from win10 to win11. I tried to use the thumbdrive but my files were too large. I also downloaded the Wave Browser,, but didn't like that. If I cancel my win10 and reinstall Thunderbird on my Win11 will it transfer? I'm looking for an easy method. I'm 83 and not that tech minded?

Hello

I have Thunderbird set up on my Android phone and I’d like to transfer the settings to my desktop (Linux Mint) Thunderbird.

The only export option that I can find on Android produces a .k9s file but I can’t find any way to load that in to Thunderbird desktop (although it worked great going from Android to Android).

There seems to be plenty of Help to go from Desktop to Android but nothing about going the other way.

There’s always the option to enter the IMAP ans SMTP settings manually but, surely, there’s a better way?

My os crashed. I have been a t.bird user for years. Luckilly took a backup file .thunderbird on flashdrive very recntly. new zorin loaded and comes with t.bird installed. i have no password. i have not yet done anything and ask for step by step help i have opened t.bird abd it asks for email and password. i did not enter anything

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.

I just installed Ubuntu 24.04.3 LTS to an old computer and I want to export my profiles and contacts from my other Windows computer Thunderbird, over to the new Linux version of Thunderbird. I suppose the other option is to re-import from Gmail contacts. Please advise. As others migrate from Windows to Linux this could be a common question.

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.

I have a new windows 11 laptop. Transferring from a windows 10 laptop. I have installed Thunderbird on new machine. It is also my email on old machine. I have clicked on import within Thunderbird. The instruction is to go to C:/Users/myusername/AppData/Roaming/Thunderbird/Profiles/b4553kng.default NB I can't find backslash on my keyboard, so I'm using / When I look in myusername, there is no folder called AppData There is a folder called Roaming, but it just has folders Intel/Wireless, which is empty. In C: Program Files, there is a folder called Mozilla Thunderbird, but it has no folder called Profiles. I have seached C: for any folder called AppData, but no results. Can anyone help?
