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?

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

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

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?

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

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!

Good morning you wonderfull people, I tend to update my computer once every so often. And that time has now come, I have to go through all the setting and extentions on my new system with Firefox along with many other settings for my faverate sorfware. Is there a way to copy all the existing settings to my new set up. Along with tool bar bookmarks that I can't seem to figure out how to export like the normal bookmarks. Kind regards Victor.

how to convert from v128.6.2 esr(32bit) to v137.0.1 (64bit)

In the past, to update the mail on another computer I simply copied the profile folder. But the new installation is now version 137.0.1 and the profile structure is very different. How do I bring the accounts and all existing mail to my new computer?

thanks for your help.

I need to import my passwords from Bitwarden. I can export them from Bitwarden as a CSV file, but that doesn't show as an option in the Import Data window in Firefox. I use MacOS 10.14.6. Thank you, Tim

I have followed all of the on line instructions to move/copy Bookmarks from Firefox Nightly (current version as of 20February025) to regular Firefox browser. Both are running on same machine. Nightly install is also running Firefox ad blockers. Following all of the instructions on line I can find to accomplish, but cannot move book marks to Firefox. Have copied bookmarks from Firefox Nightly as HTML file to stand alone device but unable to get the bookmarks to import from stand alone device into Firefox. Assistance please.

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.

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.

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've tried 7 times to import my bookmarks from Chrome into Firefox. Firefox says that the import was successful each time, but the bookmarks aren't showing up in the Bookmark Tool Bar. It's only showing the older import, not the latest. If I go to one of the new pages, it shows that it is bookmarked, but the list that it belongs to is nowhere to be found....

So how do I update to the newly imported "Imported From Firefox" folder?

Hello I have Thunderbird on my Laptop. When I try to install it on my PC I got the message: server not found. I use the same parameters than the ones on my laptop. Can I synchronize these parameters on my PC? Regards Gabriel

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).

My bookmarks in Chrome do not import into Firefox. I've Tried importing right from the Chrome browser and importing with an HTML file. No success with my bookmarks. I was able to import an extension, but I deleted it as that isn't my focus. I've checked the HTML file and it does have content (viewed in NotePad). I've looked in all the Bookmark options, but nothing imported there. I paused my NordVPN, no change. I've rebooted my desktop nothing changed. I'm running the latest updated version of Win 11.

Please advise.
