Earlier today I downloaded 102.1.2 from the website. I installed it and everything was gone. No accounts, no folders with my saved emails. So I tried overlaying the profiles with backups I created at the beginning of the month. When I launched 102.1.2 after that, I was told those profiles were incompatible and I had to set up from scratch all my folders & accounts. So I then re-installed a prior version, 91.12.0. This time I was told a newer version had set up different profiles and again, I had to start from scratch to set up Thunderbird. I'm curious how/why this happened. Can anyone enlighten me?

As it turns out, I was able to restore a system image taken last week and can run Thunderbird 91.12.0 fine. But until I can gain some understanding how to migrate to whatever new structure is in place and keep all my accounts and saved emails, I can't see updating Thunderbird any more which likely means I'll have to find another email client when I finally move to Windows 11. Hate to do that; I've been using Thunderbird for going on 20 years now. Again, can anyone enlighten me as to how I can successfully migrate my settings and saved emails to the new Thunderbird?

Any enlightenment will be appreciated!!

Hi All, I have been using Thunderbird for last 12 years and I never had issues in restoring Thunderbird PROFILE before. Today, after I reset my Windows, restoration seems not to work. I have followed all steps provided on Mozilla site and spent half day trying to figure out the problem. However, not one solution work for me. If anyone can assist, it will be helpful as I have many important data archived in that email.

Thank you.

For years I try to switch form Outlook 2010 to Thunderbird. Among others I've tried the Thunderbird Setup 31.8.0 route (partly successful, but after an update to the current version of Thunderbird, I lost all data), the new Thunderbird 102.0b4 Beta, all unsuccessfully. Like the normal version 102.0.3

I have Outlook 2010 version:14.0.7268.5000 (32 bits) and Thunderbird 102.0.3 (64bits). I choose “Import from outlook”. I get the error in a red line “no profile found”. Old agenda, contacts and e-mails are very important to me. So a clean install is not a option. If I'am not successful to migrate, I've to upgrade Outlook.

1 is 32 to 64 bits the problem? 2 is direct import from pst file possible? 3 where is Thunderbird looking for the file / profile? Is putting a copy in that location a solution? 4 other suggestions?

I Just upgraded to 103.2, When I start FF It starts with all my bookmarks pw mgr etc and I can browse to my hearts content . I use Thunderbird mail client If I click on a link for a site with a stored pw in FF password manager now I get a clean new window which has no bookmarks and no saved passwords for anything. How can you help me?

Thank you Richard

I have been using Thunderbird for some years on my laptop (Windows 10). All updates have been automatic, occuring when Thunderbird is turned on. Recently a message popped up requiring me to download an upgrade from the Mozilla website. I did so, and installed version 102.1.0. A couple of days later I received the same message when I turned Thunderbird on, and went through the same routine, installing version 102.1.1. Yesterday I received the same message, and then downloaded and installed version 102.1.2. Today I received the same message, but when I downloaded the update file it was version 102.1.2, which is already installed. In Thunderbird, when I check Help on the menu, the installed update is 102.1.2. It looks to me that something is wrong. After the initial upgrade, should further updates to it be automatic? I should not be receiving popup messages almost every day from Mozilla, and I should not constantly be going to the Mozilla webite to download and install further upgrade/update files. Thanks, Roger

After Firefox Update all data (Session, PW, ...) was lost! New version is not storing PWs, even when I click save and have activated both options for saving PWs and filling them in automatically!

I had Firefox but once it was replaced with the new version, it didn't work on my Macbook pro. I need to have Firefox on my old laptop, but its OS (10.11.6) will no longer update, and a new Firefox download won't take. When I go to the download site, it keeps downloading the latest version. How I download an earlier compatible version?

Hi, I have the latest version of Thunderbird 102.1.2 but every time I start Thunderbird I get a message saying it couldn't update automatically and asking me to download it manually. When I click on "About Thunderbird" it confirms I have 102.1.2. This has been going on for a few weeks now and I am afraid I am starting to lose patience. Does anyone have a fix please ?

Win 10laptop had Firefox installed and working. Suddenly stopped after some windows updates. I have Uninstalled several times, both vanilla and using IOBIT program. Deleted the program file folder, and the local apps profile. Won't start in safe mode either. I don't even see anything in task manager when clicking. No error messages.

However.....tried installing developer version and it works fine!

Any thoughts?

Thanks!

For the last week or two I have had an issue with Firefox closing my email (yahoo business mail) tab automatically, every time I download a file from an email.

After opening emial I click to download the file, i have the settings set to ask where I want it saved, and then either while I'm selecting the destination and labeling it, or right after the tab automatically closes. It happens both ways which suggests to me it's occurring after a specified amount of time, not based on completion of an action. And it's happening every time.

MacBook Pro Firefox 102.0.1

Any idea how to stop this?

Just installed TB102.1.2 When I try to import data from Outlook in the Import Tool I get the error "No Profile found'. Is this due to the 2 GB limitation of the tool?

I want to use two separate Microsoft email accounts on Thunderbird. I was able to add the first one using the IMAP option. When I tried to add another existing email I got the pop-up error "Incoming server already exists". I have researched this forum with no results even though this question has been posted many times. Yes, I know it is the same server, both are Microsoft accounts. They are *different email accounts using the same server*. How can I explain this to Thunderbird? I do not see any option to get past this. Any ideas?

Hi! I've searched this question but can't seem to find a "guide". I've been using Thunderbird on my PC/Laptop for at least a decade. I have a "Profile" folder but most of my mail is stored in a separate folder on my C: drive. It appears under "Local Folders" in Thunderbird. I don't know too much about Macs but just got a Macbook Pro. I've installed thunderbird and configured it to my email servers. I can get new email and now I'm at the point where I'd like to get the rest of my folders, address books, add-ons, etc. from my Laptop to my new Mac and it's a bit overwhelming. I wasn't able to export/import my address book, I've placed the .mab files in the new profile on the mac and they're not appearing and I can't help but to think that I'm missing a lot of other steps as well. I'd almost like to start over from scratch on the new Mac since my old install has been moved several times from pc to pc to laptop, etc. Any suggestions are most welcome! Thanks so much for your help in advance. PS I also had two accounts appearing on my Mac. . nyj****.net and nyj****.net (pop3). I'd like to continue using POP3. I was also able to have only 1 inbox on my PC (it was located under my "Local Folders") as well as 1 trash, etc. Can I have that again? Thanks again in advance :-)

I upgraded from Thunderbird 91.12.0 to 102.1.2 one week ago. Windows 10 21H2. I have many Saved Search folders. Since I upgraded when I click on any of them, no results (messages) are listed. If I right-click any of them, and left-click 'Properties', against 'Select folders to search' it now states '0 folders chosen', which is unexpected. I can fix this by manually re-choosing the folders for each one, but this shouldn't be necessary.

I did make a backup of my Thunderbird profile before the upgrade. I tried restoring one of the *.msf files from this backup to see if that would resolve it for the one saved search folder...but no.

Has anyone else come across this problem, and/or know a solution?

Since June 7th my gmail messages aren't downloading or sending. I have done everything suggested online to the point that I currently have the latest Thunderbird update have created a special password for apps and tried to set up the account again and it freezes after accepting the settings and the password. Any suggestions?

Right after I open or save an attachment from Yahoo Mail while using Firefox, Yahoo Mail closes all of a sudden. This just started happening about 2 months ago, in June this year. I don't think I changed any settings.

Tried updating from version 91.12.0 to 102.1.2 per About Window. After download, clicked on install but version won't update. All folders and messages are gone. Only address book is accessible. Re-installed 91.12.0 and got all mail back. What's problem with 102 or what do I do differently?

After upgrading to version 102.0.0 (Windows 8.1 64 bit) disk utilization would hit 100 % and a small white box appears lower right hand screen.

When I use the Windows supplied Task Manager, I will sometimes see 8 to 10 copies of Firefox running.
