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?

When importing logins and notes and URL from Chrome to Firefox, why the latter doesn't bring notes and read double URLs?

All of my notes are gone and if similar URLs are doubled.

Sharing one screenshot, since I cannot share another due to privacy (until a Mozilla dev team asks for it directly without sharing it on public platform).

Hello, I just used the Firefox 141.0 (aarch64) wizard for Raspberry Pi OS 1.0, to import bookmarks from Brave, however the wizard said 0 bookmarks imported.

I also manually exported and imported the bookmarks.html file and the latest bookmarks aren't appearing at the top. It seems the bookmarks are nested in some bookmarks directory by default. I'm confused?

Also I tried a manual import several months ago but same issue about some strange nesting structure rather than simply appearing at the top. Now I'm really confused and worried I'll lose my bookmarks as there's about 3 version in various nested structures. Please help just make an easy move to Firefox.

I wish to back-up my Thunderbird profile, but apparently, I am to find an "export tool" under the "tools" menu. Unfortunately the option to 'export' does not appear in the list [but "import" does...!]

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

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.

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!

I can't find the three horizontal bars to be able to access any menu, to enable me to import the passwords and bookmarks from chrome. If there's no simple solution to this, I will simply discard Firefox. All I find is three dots on the top corner and if I access settings there there are no options to import anything.

I'm sure this is a really dumb question but I'm all set to unzip my profile backup into new machine. I see it named in the Quick Access window, but a double click on it brings an error message that I have to unzip it first. Clearly I'm learning both my laptop and win 11 at the same time, and I don't know where/how to unzip it. I'm confused, I hope my question isn't. Can anyone talk me thru getting it unzipped so I can import it into Tbird in new machine? Thanks, Stacy

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!

Hi, Not sure where to begin. Had issues w/mouse and decided to reimage. Copied all files from C:\Users\user\AppData\Roaming\Thunderbird. Now have no msgfilteres, folders in Local Folders, or an Address Book.

I used info from https://windowsloop.com/backup-restore-thunderbird/. Was this wrong? Where did I mess up?

Thanks

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.

The method I found successful in creating my Thunderbird profile on a new PC was different from the posted method. I hope this method helps others. Both Ubuntu 24.04.4 Mate and Thunderbird 155.0/ On the source PC I copied the .thunderbird folder to a USB drive. On the destination PC I opened the thunderbird folder (not hidden). Copied 123xyz.default and 456pqr.default-esr to this folder. Replaced profiles.ini with profiles.ini from the source PC. Opened Thunderbird and found my familiar experience.

With a new Thunderbird installation on Windows 10 Pro, I attempted to import my profile data from a Postbox on another machine. The process failed, citing two errors (see attached screen shot), EmptyDatabase Error: "blocklists/addons-bloomfilters" has not been synced yet Uncaught NS_ERROR_FILE_NO_DEVICE_SPACE: Component returned failure code: 0X805200010

The profile being imported is pretty large -- around 20Gb, so I wonder whether I have surpassed some capacity limit. I was doing this via the Import Tool on the Tools menu.

Porting my legacy mail folders is crucial. Any help would be greatly appreciated.
