I have followed the instructions for transferring the Thunderbird profile from my old computer to my new computer. However, the updates do not come across. I don’t get all of the folders that I created on the old computer. The email works fine.

I have everything I need from my old machine except my e-mail filters. If I copy the whole profile I will lose all of the sent messages and saved messages I have generated since I got Thunderbird up and running on my new machine.

Hello, My main computer died and I am trying to setup Mozilla on a spare laptop. I exported settings from my mobile device but am not seeing a way to import them into the desktop. It created a k9s file but it is not giving that option. What am I doing wrong??

The import function does not work. I exported a Thunderbird profile in its entirety into a zip file that is only 127 megabytes when extracted. When I go to import the Thunderbird profile, I select the ZIP file, import, and it restarts, and nothing happens.

I have tried the method of going to the profile folder, manually copying the files from the extracted profile, and pasting them into the profile folder and overwriting all of the existing files, which will work for a few seconds- it briefly shows all the emails, and then they disappear. The top of the inbox indicates the correct number of emails, but no emails show up in the inbox, and when I restart Thunderbird, everything disappears.

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?

I use Thunderbird on my older Macbook Air, which I am replacing with q new Mac laptop. I have a huge record of emails in many folders on the old computer and want the same thing on the new computer. I have done this many times in the past between a desktop and a laptop Mac with no issues. But something seems to have changed.

I installed the program, I tried to transfer the profile from the old computer to the new computer, and deleted the older profile. I tried to open Thunderbird and it tells me the profile is missing or inaccessible. I deleted the .ini file but that just makes me do a set up again. I used to do this all the time between my other Macs and it was super simple. Now it's a nightmare and doesn't work at all.

So how do we transfer all saved email, folders and server into etc from on computer to a different computer?

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

bold texti have a thunderbird profile on exterior drive I have installed linux mint on my PC but cannot locate the profile to use my old TB profile -either by replacing it or renaming the old profile for the linux one

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?

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.

Having tried more than a dozen sets of downloaded instructions, including those from Mozilla Thunderbird and Apple, I have become increasingly frustrated and convinced that Thunderbird doesn't work on a MAC. Can you offer any "official" instructions? Thank you!

On my Windows 11 laptop, in Thunderbird v 148.0.1, I changed the entries for Accounts>"Your name" for all of my accounts. I then Tools>Export the settings to a file. It was reported as 1.97Gigs, and Krusader displayed it as 1.9Gigs.

On my Linux laptop, I imported the settings into Linux Thunderbird v 140.9.0esr (64-bit). It did not import the new names. When I attempted to edit them, Account Settings mode says "Account name already exists" and appends _2 to the account name.

I forgot to make a backup before I undertook this.

How can I fix this?

My desktop win 10 computer system crashed. While the operating system was zapped, the actual c: drive was intact. A new c: drive was installed with win 11 pro but when I connect the old drive to the new system, I am locked out of the user>apps>thunderbird folders ( access denied). Is there a way of overriding this security feature? I was hoping to be able to import my profile with several email addresses and their associated archival data. This is more complicated than I was expecting.

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?

I have a window home computer that was upgraded from w10 to w11. I had to buy a new w11 machine at my vacation home because the old one was not upgradeable. I was successful in moving the profile from home to vacation home. But a month later I corrupted w11 on my new vacation machine while loading my earlier version of Adobe Photoshop from their instilling disk. W11 could not be repaired and I had to reinstall new w11 while keeping my files etc. This time Thunderbird would not let me move/use my old profile file. No mater what I tried!!

In the past, I've always moved the profile file "Thunderbird" in Appdata file to the new machine and renaming the installed Thunderbird file with XXX after it. It always worked in the past. My profile file is over 2mb. I've tried using all of the logical import options in this new instillations and only get error messages that it could not import the data and to look at the error console? Which I don't know where that is located. I will look for it in w11.

I think that the only difference (which I don't think should make a difference) is the directory name file difference after "users"

Any help would be much appreciated!!!!!!!

I'm reading this> https://support.mozilla.org/en-US/kb/thunderbird-export#thunderbird:linux:tb148 Looks great but all of my messages sit on IMAP servers and I don´t need a backup of those. I _do_ need a backup of settings, passwords, pgp keys, to move to another workstation. It is unclear what exactly is exported.
