Thunderbird Community Forum

My Thunderbird Account was updated by TB on 2 September. Since then all of my new emails go to Trash. Although I've tried the various responses to such questions, I've been unable to change the problem and get my new emails to come into my Inbox. I'd very much like your assistance please. Thank you.

Thunderbird won’t open because it wants a Primary Password which I have never had to do. I went on another computer (the one that I am currently using) and generated a password for Mozilla. I tried that but it still would not open. I have restarted the computer 3 times. When it asks for the pass word, I have entered the new one for Mozilla with no success. I have tried the one for the main opening of the computer with no success. When I close the small window that asks for the Primary Password, the spinning beach ball of death shows up and eventually (maybe 10 minutes) it has to be forced to quit.

I like to know what is the problem at my e-mail setting? Since two weeks ago, when I sent a message, receiver could get my message, but there were no sent record in my Sent Message box.

This morning Thunderbird asked me to update which I duly did. Once done all messages started disappearing from inbox. Eventually I found them and moved them back to inbox only for it to happen again

Have now tried 3 times, same result, every single email from Inbox keeps being moved to deleted in Local Folders

All new emails that have come in since appear for a micro second in Inbox before being moved to Deleted

This is obviously not a great situation to put it mildly and as it has never happened before and started straight after this morning's update I can only assume that the update is to blame

Any help would be greatly appreciated

When I open Thunderbird it is sending my emails directly to the deleted folder. I have tried all-sorts and cannot find an answer. I transferred Thunderbird to my new PC and all was working okay for a few weeks then all of a sudden there were emails missing from my inboxes and I found them in the deleted folder. I am 76 years old and need an easy step by step solution please ..... John

My thunderbird would not open. Said the file location couldn’t be found. I read online it recommended that I uninstall the application and reinstall. This fixed my issue with being able to access thunderbird but during the install all of my local folders were removed. Is there anyway I can get these back? I also lost all of my address book contacts.

9.6.2026. Spoke with Spectrum, my carrier, to ensure email protocols were correct. They checked from their end and the problem is with Thunderbird protocols. There is no rhyme or reason to incoming emails. Sometimes they have their content but days have gone by where only the subject line/date/time stamp shows. What is going on???

How can I specify which Thunderbird account is used when MAILTO is used in html? I know I can change the account to what I want after the new message window comes up but I always forget.

Thunderbird not connecting to server. It says timds out and an error occurred connecting to mobile.charter.net. I can neither send or receive emails. This started 8/20/2026

Hello

I use Thunderbird (153.2 0esr) on a win 11 PC.

I have some POP email accounts with btinternet which work.

I want to change. them to IMAP accounts using the same email addresses.

Before I do this I have several minor problems within Thunderbird, which I would like to sort out before copying the Thunderbird files as a backup.

Rather than list them all, it's possible that fixing the first may solve others.

When I open Thunderbird I see this message... see FIRSTCalendar if it hasn't been inserted into the text

I have never (knowingly) used BT's calendar. Clicking cancel removes the report and does not stop any of the BT mail accounts working.

I tried using the username and password of the default account but password of the default account without success. At a later stage this appears...

See SECONDcontacts if not inserted here

The address displayed is one that I have deleted from my BT Email account.

It is no longer shown as one of my BT accounts in the email management page in MYBT or in Thunderbird

Again, clicking Cancel does not stop my BT email accounts working.

Any suggestions how to fix this, would be welcome.

Cheers

Dave

The method I found successful in creating my Thunderbird profile on a new PC was different from the posted method. I hope this method helps others. Both Ubuntu 24.04.4 Mate and Thunderbird 155.0/ On the source PC I copied the .thunderbird folder to a USB drive. On the destination PC I opened the thunderbird folder (not hidden). Copied 123xyz.default and 456pqr.default-esr to this folder. Replaced profiles.ini with profiles.ini from the source PC. Opened Thunderbird and found my familiar experience.

BUENOS DÍAS, INSTALE EL THUNDERBIRD EN MI LAPTOP, PERO POR ERROR COPIE UNA DIRECCION EQUIVOCADA,, AL INTENTAR ELIMNIARLA NO HE PODIDO POR NINGUN MEDIO, NO ME APARACE LA OPCION "Operaciones sobre la cuenta" SOLO ME SALE UNA VENTANA CON LA OPCION ESTABLECEER COMO PREDETERMINIDA Y ELMINAR PERO AL QUERER HACERLO NO SE ELIMINA.

HE ACUDIDO A NUMEROSOS VIDEOS PERO NINGUNO FUNCIONA, ME SALE UNA VENTANA EN LA PARTTE INFERIOR DERECHA QUE INDICA QUE MOZILLA NO PUEDO CONECTAR CON SERVIDOR.

HE IDO A CONFIGURACION DEL SERVIDOR, HE SEGUIDO TODOS LOS PASOS PERO NO PUEDO ELIMINAR, QUIZAS ESTE HACIENDO ALGO MAL.

YA EJECUTE COMO ADMINITRADOR, VERIFIQUE EL TEMA DE LOS CALENDARIOS Y NADA.

ESPERO QUE ALGUIEN ME PUEDA AYUDAR, QUEDO AGRADECIDO DE ANTEMANO.

This problem happened after the September update. No changes to any message filters. I am not the only one having this problem. What changed in the update that could have caused this problem? I have had to delete the problem account from Thunderbird because every time I move the messages back to the Inbox in Outlook, Thunderbird would move them back to Delete.

I am using thunderbird client on arch linux. I am trying to filter by adding "Reply-To" as a filter. If i look into the source of the email i am trying to filter (i get like 100s of spam messages and only the Reply To seems to be from the same domain in the end) the Reply-To appears in there.

Any idea how to fix that? The other rules work fine, this one only seems to not work

Please tell me how to stop this. I have spellcheck enabled and a English (UK) dictionary selected. This problem has just started. My computer is old now and I'm running Windows 10. I had to do a 'hard shut-down' recently when my computer was unresponsive - might this have caused the problem? This underlining is only happening in Thunderbird, not in Word for example. I would be grateful for a simple solution as I'm not very computer-savvy.

Twice in the last fortnight Thunderbird has lost all email passwords - the Tools/Settings/Privacy and security/Saved passwords just leads to a blank box where the passwords usually are. Thunderbird will no longer collect email and keeps asking for passwords for email accounts. This happens even when the option to 'save password' has been selected. I think this is probably happening at the point when the PC is rebooted. Thunderbird version 153.1.1esr (64 bit) and Windows 10. Using System Restore has not resulted in recovery of passwords. Several different email accounts/email providers are involved - outlook.com, tiscali.co.uk and zohomail.eu. Broadband provider is Zen.

I notice that the Appdata/Roaming/Thunderbird/Profiles/w2anb37y.default folder contains a number of files named with such names as 'logins.json-8.CORRUPT' - with 'Date Modified' being mostly either 17th August or today 31st August - so it might look as though password data is becoming corrupted.

Can you assist?

This is probably not a T-bird question, per se, but it is so strange it seems that this might be the best place to start, hoping someone might have some insight.

My wife and I each have our own laptops, running Win-11 Pro. Each laptop has T-bird 153.2.0esr (32-bit). We each have an account to yahoo mail (the site now hosting our Comcast email accounts). No problems since ... forever. Until today.

Now, beginning today, on my wife's laptop, when she opens T-bird, she gets a pop-up logon page, pre-loaded with her userid/email address. No input field for a password, but that it not unusual, as a lot of sites put that on a follow-up. But when we click 'next', it just rejects it. We were able to log into the yahoo mail web page (in Firefox) just fine.

After a lot of head scratching, I added her account to the T-bird configuration on my laptop. First time up, it prompted for credentials, but here it accepted them. So now we have her yahoo/comcast account configured and working just fine on my laptop, but continue to get credentials rejected running the same config on hers. Again, this has been working just fine up until today.

(If you are wondering about the connection between Comcast and Yahoo, several years ago we 'cut the cable' with Comcast, after confirming they would continue to support our email accounts. Then some time ago, they off-loaded that to Yahoo, such that we were able to retain our Comcast email address, but it redirected to and is hosted on Yahoo.)

Thunderbird keeps bringing in emails automatically. I don't want it to download anything until I ask it to. This just started when i had to reinstall Tbird after it stopped working for me. 1. It downloads emails automatically 2. I only want emails upon my specific request. 3. I can no longer find any switch to allow me to turn of auto downloads.
