I have Thunderbird on laptop. I make changes to a contact in the address book and they seem to be made. When I close Thunderbird and restart it, all changes are lost and are back to what the contact information was before. This has to be fixed.

This started happening a day or so ago... When I type part of an email address, Tbird shows all email addresses starting with it. Now the length is as long as the screen.. Any ideas? Thanks.

I have just used a saved email address to write an email. When I went to send it the send failed because the from account was an old account I do not use anymore.

How do I change saved email addresses so they do not use the old account.

Why would this happen.

I checked which account I was using at the time and then repeated the process with the same result. I was using my current account.

I just installed Thunderbird 154, but i cannot find the address book. i know it exists as T-bird does preload my addresses when i create a new email. Is there a button that I am not seeing?

Trying to set up a mailing list for emails. Not sure how to set up a group that I can use to list names and emails. Went to help. Instructions said to > open address book > select file > new > mailing list. I went to address book ok but cannot find 'File' there.

Am after assistance in getting mailing list set up.

Thanks

My computer had corrupt files on it, so my computer guy had to reinstall windows 11 & all my other folders to my computer. I re-installed Thunderbird with the new version 154.0 & all of my old emails are there but NO email addresses or contact addresses I had saved in there. Please help! Can I download an older version of Thunderbird 139.0.2 from June 17, 2025 for all of my email addresses to be there & contact addresses?

Until recently when using Thunderbird on my pc, android and Kindle fire HD when I start typing in a name in the TO field I see a list of possible email addresses. Still works on win11 pc, android phone but no longer on my kindle fire hd her 21.1

Contacts stopped syncing with Gmail. Followed various troubleshooting including deleting address book and trying to reinstall, and cannot reinstall Gmail address book.

My brokerage firm states that it cannot notify me via email for conformation transaction. How do I add this firm's domain to my address book so that its emails will be received my me?

When I am on my thunderbird email page and switch to page where I used to find my address book. Now all I see is an option to create a new address book. What happened to my old address book? screen shot.HEIC. screen shot.HEIC.pdf
