I try to install Firefox on a HP Z1 G8 desktop under Windows 11 Pro. The first time I get a warning that a .dll is not available or so (I dont know what this warning is precisely, becaus it pops up for 2 seconds only ) , and firefox is not well installed, reinstalling goes without warning, but still Firefox starts and then stay dead, no sites, no settings. I know the security in this computer is very thight, but other apps install without problem and functions.

Why Firefox cant be installed where other apps can ??????

who has experienced this also and has a clou ?? thanks Ferdinand

I got a new Acer laptop with windows 11 (64bit). I downloaded FF but when I open it, it just gives a blank page. If I type in an address nothing happens. I have tried reinstalling but nothing seems to work

Hi all I recently bought a new laptop that has to be exchanged as it's faulty. I had no problem moving my profile from my win 10 laptop to the new win 11 one, however I now need to put all my emails back to my old laptop and although I can go through the import procedure when I restart Thunderbird none of the new emails are there. Any help would be greatly appreciated.

Hello, I moved from TB 102 to 115 some months ago. I've just noticed that TB appears two times in my Win10 22H2 Apps & Features:

I'm tempted to use Uninstall on the 102.3.0 occurrence but I don't want to mess things up. What is the best way to remove the duplicate in Apps & Features? Thanks.

I thought I followed the instructions from thunderbird, but now all I get is thunderbird can't load because the profiles are missing or wrong. I have uninstalled thunderbird, reinstalled it, and still get the same message. I deleted the profiles in local and roaming, and reinstalled, and no profiles were created. How do I get the installation program to re-create the profiles like a new install?

HI, I have switched from Windows to Linux but I do not know how to migrate Thunderbird. I have done it before from Windows to Windows. I saved my Thunderbird folder expecting to paste it into my new OS but I cannot figure out where to paste it. Clicking on "open directory" in "troubleshooting information" does nothing. I installed Thunderbird on the new OS. I pasted the folder in the home directory and renamed it .thunderbird, but the app still does not find my data. I am using elementary OS. I am new to Linux. Step by Step instructions help a lot. Thank you for your help!

Thunderbird won't allow me to send messages after I upgraded from 31.8 to 78.14.0. The Send button is not enabled, though I do have an internet connection and have been able to receive messages. I'm pretty sure I gave the upgrade the correct email password (the same one I gave it yesterday when I installed 31.8, and which worked). Is there a way to troubleshoot or fix the problem?

Hi

My name is Ivo. I use Thunderbird for all my Email-Accounts. Now I wanted to add another one, which is info@ivo-zimmermann.ch, but it does not work (pls see screenshots in the attachment).

info@ivo-zimmermann.ch works fine when I login directly on Gmail, it also worked fine to login here into the mozilla support. Also all other accounts that I have (for example info@kanai-zimmermann.ch) were no problem to install.

Do you have an idea where the problem is?

Thank you in advance Ivo

I recently recovered the data from a corrupted laptop from 2005 that had a bunch of old emails stored in Thunderbird 1.0 using Windows XP. I would love to recover them and convert them to .mbox, but haven't found a way to convert or to install that version of Thunderbird on a modern laptop. Many thanks in advance for any advice!

I currently have TB 102 running on a Linux Mint desktop. The email is POP3 from att (actually snet). They require a different app password for each computer. I have the different app password. I want to use my Linux Mint laptop to access my email and use a backup of the desktop's profile when the desktop is out of service. Laptop does not have any .thunderdird folder yet as TB has not been started. I am looking at the http://mzl.la/1ApHiU3 support page. It seems that these instructions are replacing Laptop's hidden .thunderbird folder with desktop's .thunderbird folder. This seems odd since Step3 of "On your Destination Computer", opens Thunderbird. Won't that create a .thunderbird folder with new installs.ini and profiles.ini files? They will be replaced in Step8.

I am concerned that Step3's newly created .ini files (which have a different hash that links them) will be lost in Step8 and there is some dependency on that hash value that is not clear. Is that hash sent to the email server so that they can identify the machine/app that is accessing their server?

Is there a more appropriate support page for what I need to do? I am not clear on the subsequent steps to launch TB on the laptop and change the password on the laptop. At some point I would need to reverse the direction to bring the Laptop's Profile back to the Desktop. Any advice would be appreciated.

Hello,

I finally had to migrate my old Windows7 home computer to Windows10.

TB looks quite different from before.

After using Tools > Import to import the profile folder from the old computer, I'm having four issues:

1. For some reason, TB displays all the email accounts, although they're global: How can I get only the Thunderbird account to be displayed, like before?

2. When hitting F5 to connect and download emails from those different accounts, I'm prompted for their POP3 password. Why is that?

3. Windows won't let me unpin TB's icon in the taskbar. How can I remove it?

4. Is there a way to remove that empty space above?

Thank you.

Please help with my predicament. I had to use 38.1 to import OUTLOOK details etc. Now I want to update Thunderbird to get more functions like a dictionary etc but when I tried it messed all the settings for the email accounts and I went back to 38.1 Thankfully that worked again and I got all the settings back fine.

Please could someone help with any guidance on what version I can update to safely and step by step what I need to do?

Many Thanks

Hi

Someone please help.

I was running Thunderbird ver. 38.x.x on my Win 7 PC. All was good and never had any problems.

Recently I made the mistake to update to latest ver. 102.x.x.

This caused several issues and was not really what I was expecting. Therefore I decided to go back again.

Now I am running ver. 52.9.1. which is more or less like ver. 38. However I have one issue.

I have several IMAP mails accounts. 2 of these mail accounts are from an old mail server provider which is no longer in use. However I had access to all these older mails, which are located on my PC.

Since I did the upgrade and came back down I can no access thes older mails. When I open the account inbox, Thunderbird tries to connect to the mail server, which no longer exists.

How can I have Thunderbird to open these mails, which I assume are still located on my PC?

PS: I have even tried to install ver. 38, (same issue)

Thanks for help. :-)
