Move Thunderbird data to a new computer

I have the complete Thunderbird folder with 15 years of POP mail.

Install Thunderbird on new PC and overwrite the complete folder?

will be the same version of thunderbird.

My Thunderbird v.139.0.1 crashed. It would not run at all. I downloaded Thunderbird and it was v.139.0.2. It looks entirely different and created a new profile. I edited the Profiles.ini and replaced the new profile with the old profile. (this worked 2 months ago when I bought a new computer). Now having done the editing to get all my old emails etc, it will not bring up the old profile. How do I get my old profile and the setup from the 139.0.1 look and feel. Thanks.....

I used ImportExportTools NG to export messages from one profile and import to another.

I tried to export only selected messages from my one of my local folders (it seemed an option, but IET NG is not intuitive).

Whatever, the import process has created a sub-folder in the local folder of the same name, and there is a huge redundancy (duplication) resulting.

My question: how can I merge the sub-folder into the parent, when dragging and dropping is not allowed?

I recently deleted a gmail account from my TB. It was a shared account so that account is still open but I have no more need of accessing it. So I went into my TB\Account Actions\Remove Account. It no longer exists on my main TB page which shows my different email accounts. Suddenly, and constantly, I have this window pop up, requesting my login info, which I no longer have. When I close the window, it just opens back up. I have to close it in order to get to my main TB window. It's horribly frustrating. Any ideas??

Hi! I'm trying to set Thunderbird as the operating system default under Win 11. I tried to follow Mozilla's instructions: 1. Open the Settings application by pressing and releasing the Windows Start button, then clicking the gear icon. 2. Click the Apps icon, then click Default Apps in the list. 3. Click the icon under the heading Email to show your choices. 4. Select Thunderbird. The trouble is that at n. 3 there is no choice. There is only 'OutlookAccounts' and this item cannot be deleted or replaced. Can you help? All the best, Robifiori

Guten Tag, ich arbeite mit Thunderbird auf Linux Mint. Jeweils in den aktuellsten Versionen: Linux Mint 22.1 Cinnamon Thunderbird 128.11.0esr (64-Bit)

Auf meinem bisherigen Rechner begann Thunderbird mit dem letzten Upgrade von Linux Mint langsamer zu laufen. Da ich mir nicht anders zu helfen wusste, habe ich in einen neuen Computer investiert. Obwohl der Rechner jetzt deutlich performanter sein sollte, hängt Thunderbird mindestens genauso wie vorher. Zum Teil ruft Thunderbird auf dem neuen Rechner auch keine neuen E-Mails mehr ab. Ein Neustart korrigiert das zwar wieder, aber beim nächsten Start kann es dann wieder genauso sein.

Alles, was man in den Foren findet, um Thunderbird schneller zu machen, habe ich erledigt. Cache gelöscht, im abgesicherten Modus gestartet (da ist Thunderbird genauso langsam). Auch verschieben von Nachrichten in Archivordner brachte keine wirkliche Besserung.

Ich nutze Thunderbird für 7 Kalender (zum Teil lokal) und 10 E-Mail-Adressen bei unterschiedlichen Anbietern.

Als Add-on habe ich DKIM Verifyer installiert und aktiv.

Ehrlich gesagt, bin ich inzwischen ziemlich verzweifelt, was das Thema angeht. Witzigerweise lassen sich die Entwicklerwerkzeuge nicht aufrufen. Keine Ahnung, ob das vielleicht ein Indiz für den Fehler sein könnte.

Hat jemand eine Idee? Oder noch Fragen?

Herzlichen Dank.

I am having some trouble getting Thunderbird to display all my messages. I tried troubleshooting mode and found that all the messages were displayed. Restarting in normal mode having disabled my extensions and hardware acceleration, the problem returned and I could not see most of my messages. So I need to make the other changes that troubleshooting mode makes. These are described at https://support.mozilla.org/en-US/kb/troubleshoot-mode-thunderbird as

• Window and sidebar size and position settings (described in terms of Firefox)
• userChrome and userContent customizations ; see userChrome.css and .js and userContent are unsupported

I do not understand what these are and how I can set them for routine use. Can someone point me to an explanation? Thanks.

Can emails written be delayed in sending - this may be important in writing to different world time zones preventing email to be received by recipients at night times or hoidays.

When I click on an email in my mail 'inbox', items open in a 'send' window? Why don't they open into a 'read' window? Why are emails opened with red outline boxes and largely inaccessible? Can you help? Must I reload Thunderbird and Firefox? Are there tweaks that I am missing. I have spent several hours trying to sort this out, so far no luck!! Can you help?

AOL made me do a 2 step verification and now Thunderbird won't connect to AOL. Thunderbird keeps asking for my AOL password, which I enter, but it won't connect. I'm guessing it's because AOL wants the code that they text me before allowing a connection. So if this is the case, how do I get around it? Thanks much for any help.

I recently installed Thunderbird on a new Windows 11 PC. I am using Thunderbird 128.11.0esr on another machine and it works properly. I attempted to clone my 128 setup onto the new machiine by copying the Profile folder without success. Some settings were transferred, enough so that the inbox was filling with my emails. I tried to send a message. It failed with the message: "Sending of the message failed The message could not be send because the connection to Outgoing server (SMTP) smtp.gmail.com times out. Try again" As far as I can tell the SMPT server settings are exactly the same on the two setups: Description: Gmail Port: 587 Connection security: STARTTLS Authentication methon: OAuth2 Username TMerrillH Sending GMail using the GMail app works properly. Could it be something in the OAuth2 system?

Sometimes message pane box got blank on one or two of the messages. I tried disabling hardware acceleration, did not help. I can clear by restarting Thunderbird. What is causing this? I am on a Mac M2 processor.

Can anyone tell me how to set up the THUNDERBIRD TO ALWAYS LOG-IN into its own Messenger and avoid the Yahoo's interference with his INADEQUATE Messenger format - this should not be high-science question but I have difficulties to find an information in the HELP-section - thanks, Tony H. ...!

I have mail in my calendar. [email removed]@gmail.com there is a reminder in the calendar. As a task. I can't delete it. Server error. It is not available on the Gmail server.

Group contacts have been established and the group is listed in the Address page. An email is prepared and the group name is inserted in the bcc slot. An x appears to the left of the group name. The Send button is grayed out and the email can't be sent. What is the problem?

I have around 2000 emails in TB but it is not syncing to my gmail account (only 1000 synched). How do I refresh/continue the synch? It stopped after emails from year 2018 but there should be emails there from year 2013. Thanks so much.
