I'm trying to transfer the Profile folder from my current laptop to my new one. I followed the directions here: https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer but must've made a mistake because none of my many Local folders have populated Thunderbird in the new laptop. Also, the GB size, number of files and number of folders show to be very different on the new laptop vs. the current one.

I'm inclined to just start over but have a question. Can I simply delete the contents of the "Thunderbird" folder under "Roaming" in my new laptop and try again to paste into it? Or are there some items in that folder that were inserted when I first downloaded TB into my new laptop so that doing a complete deletion would remove those and they wouldn't be replaced when I try pasting again? If so, how do I get around that?

Thanks very much for your help.

I had a computer crash recently and my calendar won't save a new entry (and has no entries). How do I remove and reinstall (refresh) the calendar? Thanks for any help. My Thunderbird is 128.4.4esr (64-bit). My OS is Ubuntu 24.04.1

I am trying to install Thunderbird with my email server being Canadian (i.e. Shaw email) and an error message continues to pop up with no apparent solution. The error message is "incoming server already exists" Below is Shaw's solution which doesn't work.

Account type: "IMAP Username: Shaw email without @shaw.ca Password: My Email address; bgbraun@shaw.ca Incoming server: imap.shaw.ca Incoming server security Type: SSL (SSL/TLS option in Thunderbird) Incoming server port: 993

SMTP server settings Description: anything I want Server name: mail@shaw.ca Port: 25 Default: 587 Do you suggest changes?

I have to use ctrl - many time to see everything on my screen. I promise, I didn't change anything, just updated. I'm not super literate about things like this and my IT husband has gone onto his next adventure. I'm hoping for a simple fix. Thanks.

Bonjour à tous J'ai essayé de toute sorte de manière de me servir de Thunderbird pour envoyer des photos avec le (menu contextuel, envoyer vers le destinataire) Il fonctionne avec Windows 10. Je peux faire fonctionner Microsoft Outlook, mais pas Thunderbird avec Windows 11 pourquoi? J'ai fait toutes les paramètres mise par défaut, ainsi que mail to.

Toutes mes choses sont dans Thunderbird et je l'aime plus que tout (connait plus). J'aimerais beaucoup si vous pourriez m'aider, je vous en remercie à l'avance.

Back in September, 2024, Microsoft Outlook no longer accepted my long-used login information via Thunderbird. I could still log in to https://outlook.live.com/owa/?realm=hotmail.com from the Firefox browser. I tried adjusting Account Settings (e.g. Server Name, Server Type [POP], Security/Authentication, etc. to no avail. I downloaded the current version of Thunderbird (128?) and tried installing per directions found here. Tried using the Flatpak path. The direct Command Line path yielded the same result.

dave@Sequimer:~$ sudo flatpak install flathub org.mozilla.Thunderbird [sudo] password for dave: Skipping: org.mozilla.Thunderbird/x86_64/stable is already installed

On edit: Did what I hoping to avoid and deleted Thunderbird and all of the Thunderbird related files in the Linux home directory. Then installed a current version of Thunderbird and imported email stuff from an earlier backup. It works but now I have two renditions of Thunderbird running simultaneously.

I use a Firefox browser and a few days ago I got a message on my screen saying I wouldn't be able to use it after January 2025. I didn't read the message properly so I can't give any details.

I have looked at system requirements to update my current version but as I will explain it is not possible for me to update: I am using an old iMac - OS X version 10.9.5 The firefox version is 78.15.0esr (64-bit)

To update I need to have at least Mac OS 10.12 or later.

I am not computer literate so I cannot update my Operating System so I won't be able to download a more recent version of Firefox browser.

• Will my current version still work after January (but with no new security updates)?
• or will I not be able to use my Firefox browser at all?

Hi Ive just installed macOS Sequoia and Firefox is really slow and showing a refreshing spining icon with a few tabs open, this never happened before the update. Is there anything I can do?

M2 Mac Mini 2023 running MacOS Sequoia 15.2. Firefox will not open after upgrading to MacOS 15.2. Searching online both Mozilla and Apple recommend uninstalling Firefox by dragging the app to the Trash and reinstalling. However, the Mac won't allow me to drag Firefox to the Trash. There are no Firefox processes running in Activity Monitor and the Firewall is turned off. Also, I'm unable to start Firefox in safe mode. I deleted the Library folder in Application Support for Firefox and still can't open the app or uninstall it. If I attempt to install a new copy of Firefox over the existing app I get the error message shown in the screenshot below. Can anyone suggest how to fix this?
