Hello - My Thunderbird address book has disappeared. I used to access it in the Tools menu, but Address Book is no longer an option in the menu. There are still several abook files in the profile folder, but no way to access them. I think this happened after a recent Thunderbird update, but I am not sure which one. I am currently on version 140.1.0esr (64-bit), on Windows 11 Home version 24H2. Thanks. Glen

I am trying to add a new email to Thunderbird. When I select Add Account I get the Account Hub modal to enter Name and email address. I then press continue and all I get is a spinning blue disk. There are no options to enter the details manually.

I'm using version 140.1 I've looked at Automatic Account Configuration but that only seems relevant up to v128 and Manual Account Configuration hasn't been updated in 7 years.

(The email account is working because I've sent emails from another computer).

A number of times when I'm answering email and need to check back on the list of emails, I don't see a Tab to take me directly to my list of email accounts (I have 8). A couple of times I've had to shut down T-bird and re-launch it to get back to this list/window. I don't understand why such a Tab isn't available everywhere.

So I'm looking for an add-on which would allow me to add a specific Tab on the T-bird pages where it isn't there, specifically, a Tab to get to the window which has the list of my email accounts.

If there is such a customization, I'd appreciate getting a link to get it.

My windows 11 computer stopped accessing yahoo mail. I get message

Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.

I have tons of space.

Hjälp! Jag kan inte skicka mail längre! Efter senaste automatiska uppdateringen av Thunderbird (som gjordes för ett par dagar sedan) går det inte att skapa nytt meddelande. Knappen "Nytt meddelande" reagerar inte när man klickar på den. Vad kan man göra åt detta? Vänligast Hasse Svenson

I have just set up Thunderbird with a handful of email accounts.

All inboxes show in the "All Folders" panel block, but when "Unified Folders" block is selected, the accounts prefixed "Intuition" fail to show in the panel. The Unified Inbox DOES receive mail from these hidden accounts, but this isn't really good enough as I need to be able to browse in to the folders within these accounts regularly.

Having both Unified and All views up is a workaround, but with 10+ accounts it takes up the full length of the screen when collapsed and is not the ideal setup.

I have deleted the folder index json and a couple of other internet-sourced tricks but to no avail.

Image attached - accounts prefixed "intuition" are the culprits!

Some of my calendar reminders are not appearing. At least one in particular is still showing. This is a daily reminder. Other reminders whether for a set period or just a one off do not appear.

I am using Version 140.1 on Firefox.

Hello,

After the automatic update of Thunderbird Destkop (Windows 10) to version 1.140.0 and then a manual update to 141.0, I cannot send emails using port 587 with STARTTLS (e.g., for an account hosted at smtp.office365.com).

Sending mail from other accounts via port 465 using SSL/TLS still works. Also, using an older version for Linux with the same setting for port 587 works.

Does anyone else experience a similar problem? Has there been a change in the implementation of STARTTLS?

macOS 15.5, TB 141. By design, when one "Removes" a profile without deleting the data, the profile no longer appears in Profile Manager, but it is still in the profile folder. Thus, is it safe to manually delete a "removed" profile if one later decides it is not needed?

Thank you.

I am suddenly unable to create new messages in Thunderbird. If I try to click new message or the message area on the taskbar it does nothing. It will also not work in troubleshooting mode. I am using version 141.0 64 bit.

Since updating to 141.0 64 bit today (Jul 22, 2025) my addon Filtaquilla is disabled.

I tried another attachment saver and the same thing happened. Okay, I'll revert back to previous version.

Can't do that without starting a new profile.

Sure glad I donated to Thunderbird last night.

Yesterday night Thunderbird updated to 140.1.0esr on my Windows PC. The "new message" button no longer works. The button registers that I press it (short-term slight color change of the button), but a new message is not opened. Ctrl+N does not work either. Everything else seems to work in Thunderbird - for example, I can reply to emails.

What settings do you suggest to allow access to my att email account? I am using Thunderbird V 140.0.1 esr on an iMAC running iOS 10.15.7. The attached screenshots show the results of attempts to re-establish the account and the resulting error messages. It appears that the server settings need tweaking, since the user name and password are those I use to log in successfully to the att account with both Firefox and my iPhone. Thank you, Vince K.

after the last update 141.0, it is not possible to create a new message, neither via the speed dial button nor the New Message button nor ctrl+N po poslednej aktualizácii sa nedá vytvoriť nová správa, ani cez tlačidlo rýchlej voľby, ani Spáva- nová správa, ani ctrl+N

I was forced to erase my PC because it was infected with malware. I saved my Tbird profile to my HDD before erasing. I pasted the saved profile to %Appdata% >Thunderbird, copying 1,777 items. When I brought up Tbird, I got the Account Setup window, so I don't think the profile was actually there. What did I do wrong?

MacOS 15.5. I’m running ver 128 ESR. I want to update to ver 141 Release.

I made certain that I have a backup of my current profile. Then I downloaded the 141 dmg and copied the application into a subfolder (called Internet) in /Applications, which is where verion 128 resides.

I opened version 141, and was presented with a window asking me to perform a complete, new setup. Why doesn’t version 141 find my (ver 128) default profile, which is named xxxxxx.default?

I quit version 141 without performing the Setup. There are no new files in my profile folder (and version 128 seems to be working normally).

Thank you.

I have created several gmail addresses

But there is 1 address that is impossible to add to Thunderbird.

I always get the same error message.

the address and password are correct. I checked on my browser with the gmail box.

I've deleted, manually changed the password in Thunderbird but nothing. the synchro is impossible.

However, the other emails work perfectly.
