Thunderbird Support Forum

I'm a newbe Thunderbird user making the transition from Outlook which I've used for years but recently discovered is too compromising especially when it comes to archiving. Have been using Mozilla for years on a Surface laptop (windows 11), Cyberpower desktop (windows 10), and Android Note 20. I've downloaded Thunderbird and it is working fine. Where can I find user training videos for Thundbird, especially archiving? Are there other ways besides on-line gifting in which I can contribute to the research that makes Mozilla and Thunderbird possible? Thank you.

Emails with different subjects are getting threaded together. For example, in the attached snapshot, why are the emails with subject "Bid S011090833" getting threaded under "Hein Revised Hall Bath..."?

Perhaps I don't understand how Thunderbird determines messages have a common thread.

Using Thunderbird 115.4.1 (64-bit)

I want to turn off ALL threads in Thunderbird.

Just the last two days TWO IMPORTANT messages (from two different people) on my computer did not display in my email feed, I only saw them by accident on my phone..

I have searched very, very many times to change the settings, but regardless of what I do, it doesn't help..

I have tried "View / Sort by / Unthreaded", it doesn't work.. I have tried to look for the "Organize Mail by Thread" in Settings, I cannot find it. I have spent SOOOO much time trying to find out about this, but not been successful... (It is NOT the first time this has happened!)

Can anyone help??

Please tell me how to get my address books back after moving to a new computer. I have thunderbird, and I've gotten my inbox moved, but my address books are empty. I had hundreds of contacts. How do I get them back. I've tried the import tab but it only wants to import from a file on my computer. As I understand it, my provider keeps data such as this, I just need to know how to access it. My internet provider is Optimum/

I'm trying to export my Thunderbird addressbook using the export function. I go to "address book"->"tools"->"export" and I get "Export Export accounts, messages, address books, and settings to a ZIP file. If your current profile is larger than 2GB, we suggest you back it up by yourself." Then it wants to export the whole thing as a Thunderbird Profile with no other choices showing. I can't seem to export the "address book" to the "csv" format which I used to be able to. Any ideas?

I have Backed up my whole system with Windows 11 Backup (because I was having problems with Edge and Windows Explorer) and saved the backup to another HD in the PC. I am having great trouble trying to restore my Address books and Mail in Thunderbird. There are multiple Profiles in my Thunderbird so picking the correct one is just a guess. Is there any chance of getting my Address book (mainly) and my Mail back? Kelvin

Befor the Firefox upgrade my in box was split in two. The top half was the messages and the bottom half a preview of the message. Now I just have one long list of emails. Please can you advise how to go back to the split screen view. Many thanks. Joe

How can I delete a second email account folder that duplicates data in 1st folder? Folder names are as follows: prentissr@ example.net prentissR@ example.net

Thunderbird will not accept my reset passwords and there is no method to reset the passwords. I have tried 5 times, no help.

Cancel my subscription if I can't get help.

My email sends a note that my email has been suspended and I need to work

/moved thread from Firefox to Thunderbird Support section since the image was about the Thunderbird email client..

I used to backup firefox & thunderbird profile using MozBackup and it saved it as a pcv. When my computer crashed I need to get another motherboard & hard drive and now I seem not to be able to restore my profile using Mozbackup. It says everything was ok but has not restored profile in thunderbird. Can anyone help as there are important emails I need to reply to and with out my old profile I cannot reply.

I have 2 email accounts on Thunderbird, a Yahoo account and a GMAIL account. Whenever I receive an email on either account, it appears as an email on BOTH accounts. This results in a completely duplicate list of emails on both accounts. My intention is for incoming emails to appear only on the account to which they were sent. How do I accomplish that? Thanks in advance for any suggestions!
