I exported my profile to an external drive, then reset my Windows 11 PC. The resulting file is a zip file. When I import, the import starts, then stalls and gives an error. The error log is incomprehensible to me. How can I not lose my local folders and messages? I tried unzipping and importing that folder, but another error. I need help! Ideas? Thanks.

I am new to Firefox and tried to import the Google Chrome Bookmark Toolbar bookmarks. This did not happen and need to get the items listed in the Chrome Bookmark Toolbar into my Firefox Browser.

I have a huge and vital archive of past emails in Thunderbird on my old Windows 10 PC. The hard drive containing the Thunderbird profile has now failed and I can't access its contents. I have a new Windows 11 PC and have installed Thunderbird on it. I thought I had backed up my Thunderbird profile on an external drive, so have copied this backup onto the new PC, and have tried to use Thunderbird's Import function, but I get an error message each time, saying 'import failed unexpectedly'. The backup I'm using was saved using a data backup program called Bvckup2 and consists of folders called '$Archive', 'Cache2', 'Safebrowsing' and 'StartupCache'. Am I doing something wrong? Is it possible I've been backing up the wrong thing? Am I going to have to send the failed hard drive to a data recovery specialist and hope that they can access it?

I copied my home page from my old installation to another (new computer) - yadda.htm

I found out that the bookmarks toolbar is Installation Specific (boo) and that the export/import process on Firefox for the toolbar (according to Google) is hidden, convoluted. and a complete enigma (to me - can't be easy for anybody, really)

Could you please tell me how I can add to my new bookmarks toolbar from my old browser/installation without having to recreate them from scratch at my new installation?

Thank you.

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 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.

Hi Firefox I installed Firefox and I have a problem with transferring passwords from Chrome to Firefox because I don't see the option to export hala to it, how can I do it and do I need the PC version to do it? Best regards, Kacper.

I have the Android version of Firefox

I've usede Safari for years, but want to try Firefox. I've tried to import data, bookmarks and so from safari, but can't do it. Firefox says: Select the Safari file. But which one? And where do I find it? I've find the app Safari – but there's a lot of files underneath it.

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 have used Firefox for many years without opening a Firefox account and have accumulated many bookmarks. My computer has just had its operating system and solid state hard drive replaced and all of the old files and data transferred to the newly installed hard drive. I just now opened a Firefox account so I could ask the question about how I might recover the bookmarks and load them in Firefox. After reading some of your support pages it seems likely that the bookmark file was transferred into the new operating system. I would like to find out how these old bookmarks can be loaded to the Firefox program now loaded onto my computer.

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 am on Thunderbird Flatpack version 115.5.1 and I want to transfer to Thunderbird for Android, how do I do that, please? I am running on Chromebook using the Linux partition. I have exported the profile to a zip file, but Thunderbird for Android won't read it. The zip file is 2.5GB so maybe it is too big. But I am not adept at Linux and I can't find my way to the profile files for a manual copy. When I go into Troubleshooting Information the Profile Directory - Open Directory button does nothing. Alonside it it says "(Lolcal drive)". Maybe I should upograde Thunderbird first, but how do I do that, please?

I am trying to setup Thunderbird on a new Windows 11 PC. My current PC is running Windows 10. I am thoroughly frustrated to the point where I might just switch to Outlook!

First some basic parameters.

On a "techie" skill level I am about a 3 on a scale of 10. I have been a Thurderbird user for a long time, 15+ years. The Thunderbird version on the Windows 10 PC is 140.3.1esr(32-bit) The Thurderbird version on the Windows 11 PC is 143.0.0(64-bit) I managed to stumble through a Thunderbird migration change 6 years ago when I purchased my current Windows 10 PC.

Here are the issues I am having.

1. I do not know how to locate and transfer to the new PC all of my contacts. 2. I do not know how to locate and transfer the sent mail history. 3. The Windows 11 PC version is not synchronizing with the mail server (Comcast.net). When I read, delete, or move an email it is still showing as unread on my other devices. (The Windows 10 PC, iPad, iPhone) Conversely, if I read an email on one of the other devices, it still shows as unread on the Window 11 PC. 4. The is no Junk mail showing in the Junk folder on the Windows 11 PC, but junk mail will show in the Junk folder on the Windows 10 PC. I clean the Junk folder regularly. However, the junk mail is being filter out on the Windows 11 PC because it is not showing in the Inbox. 5. (Somewhat minor) On the Windows 11 machine the preview panel is on the right. On the Windows 10 machine the preview panel on the bottom. I prefer the bottom. I don't see in settings were to change this.

What I have done so far: 1. I compared setting for setting from the old PC to the new PC. I noticed in the new Windows 11 version there is no settings called "Message Synchronizing". 2. I was able to locate the file that contained all of my local files. I copied it to the new PC and directed Thurderbird to use this file. Works fine. 3. I have read the Help instructions for "How do I find my profile", "Moving a profile", Backing up a profile", Restoring a profile backup", Method using a transfer device", and "An alternative method for manual transfer between Windows 10 and Windows 11 computers".

As state above, my skill level is about a 3. When I start dealing with hidden files I am getting beyond my skill level.

My questions are: 1. Since Thunderbird seems to be setup and running, although not how I like, is it necessary to do the transfers described in the Help articles. Would I be over writing the manual setup I have completed when I compared the setup pages from the old and new PCs? 2. Can the files name for where the contacts are store be provided so I can manually copy over? I would think this would not be a hidden file. 3. How do I get the Windows 11 version to synchronize with the Comcast mail server? If the synchronizing occurs, will I get all of the "Sent" history or is this in a file that needs to be copied. FYI, the emails I sent from the Windows 11 PC has synchronized to the Windows 10 PC. 4. What are the settings for the Junk mail. The settings on the Windows 10 PC and the Windows 11 PC are the same. 5. Last but not least, how do I get the preview pane on the bottom. :-)

Thanks, and HELP!

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!

Problems with importing a profile having successfully exported it. As the profile is larger than 2GB I couldn't create a ZIP file. Having imported the profile my historical emails are not showing.
